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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
