Devicetree changes for omaps for genpd support for v5.13
In order to move omap4/5 and dra7 to probe with devicetree data and genpd,
we need to add the missing interconnect target module configuration for
the drivers that do not still have it. This is similar to what we have
already done earlier for am3 and 4 earlier.
These patches are very much similar for all the three SoCs here. The dra7
changes were already available for v5.12 merge window, but were considered
too late to add for v5.12. The patches for omap4 and 5 follow the same
pattern, except for PCIe that is available only on dra7.
We do the changes one driver at a time, and still keep the legacy property
for "ti,hwmods" mostly around, except for cases when already not needed.
We will be dropping the custom property and related legacy data in a
follow-up series.

All of the currently known MStar/SigmaStar ARMv7 SoCs have an "xtal"
clock input that is usually 24MHz and an "RTC xtal" that is usually 32KHz.
The xtal input has to be connected to something so it's enabled by default.
The MSC313 and MSC313E do not bring the RTC clock input out to the pins
so it's impossible to connect it. The SSC8336 does bring the input
out to the pins but it's not always actually connected to something.
The RTC node needs to always be present because in the future the nodes
for the clock muxes will refer to it even if it's not usable.
The RTC node is disabled by default and should be enabled at the board
level if the RTC input is wired up.

In preparation for probing l3 with simple-pm-bus and genpd, we must move

We need mmio-sram early for omap4_sram_init() for IO barrier init, and
will be moving l3 interconnect to probe with simple-pm-bus that probes
at module_init() time. So let's move mmio-sram out of l3 to prepare for
that.
Otherwise we will get the following after probing the interconnects with
simple-pm-bus:

We can now probe devices with device tree only configuration using
ti-sysc interconnect target module driver. Let's configure the
module, but keep the legacy "ti,hwmods" peroperty to avoid new boot
time warnings. The legacy property will be removed in later patches
together with the legacy platform data.
Note that the old sysc register offset is wrong, the real offset is at
0x1100 as listed in TRM for SATA_SYSCONFIG register. Looks like we've been
happily using sata on the bootloader configured sysconfig register and
nobody noticed. Also the old register range for SATAMAC_wrapper registers
is wrong at 7 while it should be 8. But that too seems harmless.
There is also an L3 parent interconnect range that we don't seem to be
using. That can be added as needed later on.

In order to update pcie to probe with ti-sysc and genpd, let's update the
pcie ranges to not use address 0 for 0x20000000 and 0x30000000. The range
for 0 is typically used for child devices as the offset from the module
base. In the following patches, we will update pcie to probe with ti-sysc,
and the patches become a bit confusing to read compared to other similar
modules unless we update the ranges first. So let's just use the full
addresses for ranges for the 0x20000000 and 0x30000000 ranges.

After updating pci-dra7xx driver to probe with ti-sysc and genpd, I
noticed that dra7xx_pcie_probe() would not run if a power-domains property
was configured for the interconnect target module.
Turns out that module_platform_driver_probe uses platform_driver_probe(),
while builtin_platform_driver uses platform_driver_register().
Only platform_driver_register() works for deferred probe as noted in the
comments for __platform_driver_probe() in drivers/base/platform.c with a
line saying "Note that this is incompatible with deferred probing".
With module_platform_driver_probe, we have platform_driver_probe() produce
-ENODEV error at device_initcall() level, and no further attempts are done.
Let's fix this by using module_platform_driver instead.
Note this is not an issue currently as we probe devices with simple-bus,
and only is needed as we start probing the device with ti-sysc, or when
probed with simple-pm-bus.
Note that we must now also remove __init for probe related functions to
avoid a section mismatch warning.

When moving the l4 interconnect instances to probe with simple-pm-bus and
genpd, we will have l4per and core domains stop idling unless we configure
the domain bits to allow retention when idle.
As the TI SoCs have hardware autoidle capabilities, this is safe to do.
The domains will only enter retention on WFI when none of the devices on
the domain block autoidle in the hardware. This follows what we are
already currently doing.
