Interacting with the GSP currently requires using definitions from C
header files. Rust definitions for the types needed for Nova core will
be generated using the Rust bindgen tool. This patch adds the base
module to allow inclusion of the generated bindings. The generated
bindings themselves are added by subsequent patches when they are first
used.
Currently we only intend to support a single firmware version, 570.144,
with these bindings. Longer term we intend to move to a more stable GSP
interface that isn't tied to specific firmware versions.

570.144 is the latest available into linux-firmware as of this commit,
and the one we will use to start development of nova-core. It should
eventually be dropped for a newer version before the driver becomes able
to do anything useful. The newer firmware is expected to iron out some
of the inelegances of 570.144, notably related to packaging.

The GSP bootloader is a small RISC-V firmware that is loaded by Booter
onto the GSP core and is in charge of loading, validating, and starting
the actual GSP firmware.
It is a regular binary firmware file containing a specific header.
Create a type holding the DMA-mapped firmware as well as useful
information extracted from the header, and hook it into our firmware
structure for later use.
The GSP bootloader is stored into the `GspFirmware` structure, since it
is part of the GSP firmware package. This makes the `Firmware` structure
empty, so remove it.

The GSP firmware is a binary blob that is verified, loaded, and run by
the GSP bootloader. Its presentation is a bit peculiar as the GSP
bootloader expects to be given a DMA address to a 3-levels page table
mapping the GSP firmware at address 0 of its own address space.
Prepare such a structure containing the DMA-mapped firmware as well as
the DMA-mapped page tables, and a way to obtain the DMA handle of the
level 0 page table.
Then, move the GSP firmware instance from the `Firmware` struct to the
`start_gsp` method since it doesn't need to be kept after the GSP is
booted.
As we are performing the required ELF section parsing and radix3 page
table building, remove these items from the TODO file.

The Booter signed firmware is an essential part of bringing up the GSP
on Turing and Ampere. It is loaded on the sec2 falcon core and is
responsible for loading and running the RISC-V GSP bootloader into the
GSP core.
Add support for parsing the Booter firmware loaded from userspace, patch
its signatures, and store it into a form that is ready to be loaded and
executed on the sec2 falcon.
Then, move the Booter instance from the `Firmware` struct to the
`start_gsp` method since it doesn't need to be kept after the GSP is
booted.
We do not run Booter yet, as its own payload (the GSP bootloader and
firmware image) still need to be prepared.

When all the firmware files are loaded from `Firmware::new`, it makes
sense to have the firmware request code as a closure. However, since we
eventually want each individual firmware constructor to request its own
file (and get rid of `Firmware` altogether), move this code into a
dedicated function that can be called by individual firmware types.

There are a few cases where we need the lowercase name of a given
chipset, notably to resolve firmware files paths for dynamic loading or
to build the module information.
So far, we relied on a static `NAMES` array for the latter, and some
CString hackery for the former.
Replace both with a new `name` const method that returns the lowercase
name of a chipset instance. We can generate it using the `paste!` macro.
Using this method removes the need to create a `CString` when loading
firmware, and lets us remove a couple of utility functions that now have
no user.

Right now the GSP boot code is very incomplete and limited to running
FRTS, so having it in `Gpu::new` is not a big constraint.
However, this will change as we add more steps of the GSP boot process,
and not all GPU families follow the same procedure, so having these
steps in a dedicated method is the logical construct.
There is also the fact the GSP will require its own runtime data, and
while it won't immediately need to be pinned, we want to be ready for
the time where it will - most likely when it starts using mutexes.
Thus, add an empty `Gsp` type that is pinned inside `Gpu` and
initialized using a pin initializer. This sets the constraint we need to
observe from the start, and could spare us some costly refactoring down
the road.
Then, move the code related to GSP boot to the `gsp::boot` module, as
part of the `Gsp` implementation.
Doing so allows us to make `Gpu::new` return a fallible `impl PinInit`
instead of a `Result.` This is more idiomatic when working with pinned
objects, and sets up the pinned initialization pattern we want to
preserve as the code grows more complex.

We want to store the GSP and SEC2 falcon instances inside the `Gpu`
structure, but doing so require these types to implement `Send` for
`pci::Driver` to remain implementable on `NovaCore`, which embeds `Gpu`.
All implementors of `FalconEngine` and `FalconHal` satisfy the
requirements of `Send`, and these traits also already required `Sync`,
so this a minor tweak.

pin-init changes for v6.18
Changed:
- `#[pin_data]` now generates a `*Projection` struct similar to the
`pin-project` crate.
- Add initializer code blocks to `[try_][pin_]init!` macros: make
initializer macros accept any number of `_: {/* arbitrary code */},` &
make them run the code at that point.
- Make the `[try_][pin_]init!` macros expose initialized fields via a
`let` binding as `&mut T` or `Pin<&mut T>` for later fields.
Upstream dev news:
- Released v0.0.10 before the changes included in this tag.
- Inform users of the impending rename from `pinned-init` to `pin-init`
(in the kernel the rename already happened).
- More CI improvements.

We already have dedicated helper macros for printing GT-oriented
messages but we don't have any to print messages that are tile
oriented and we wrongly try to use plain drm or GT-oriented ones.
Add tile-oriented printk messages and to provide similar coverage
as we have with xe_assert() macros. Also add set of simple macros
for the top level xe_device, which we could easily tweak to include
extra device specific info if needed.
Typical output of our printk macros will look like:
[drm] this is xe_WARN()
[drm] *ERROR* this is xe_err()
[drm] *ERROR* this is xe_err_printer()
[drm] this is xe_info()
