ASoC: AMD: ACP7.x initial PCI driver bring-up

Vijendar Mukunda <Vijendar.Mukunda@amd.com> says:

This series adds initial AMD ACP 7.x support for ACP7.D / 7.E / 7.F
platforms.

Compared to earlier ACP generations, ACP7.x includes substantial design
changes, including an updated register set/layout. For that reason,
the ACP7.x implementation is placed under a separate sound/soc/amd/acp7x/
directory instead of extending older-generation code paths,
keeping ACP7.x-specific logic and register definitions cleanly separated
and easier to maintain.

This initial version is intentionally focused on the core PCI driver
bring-up: register definitions, probe/remove, basic helper wiring, and
system sleep + runtime PM integration. A follow-up series will add support
for additional Audio I/O blocks, including SoundWire and the ACP PDM
controller.

The primary goal of this series is to unblock power validation, since the
ACP IP currently does not have a driver available with PM ops support on
these platforms.
