58e82a6266 platform/x86/amd: Add support for AMD ACPI based Wifi band RFI mitigation feature
Due to electrical and mechanical constraints in certain platform designs
there may be likely interference of relatively high-powered harmonics of
the (G-)DDR memory clocks with local radio module frequency bands used
by Wifi 6/6e/7.

To mitigate this, AMD has introduced a mechanism that devices can use to
notify active use of particular frequencies so that other devices can make
relative internal adjustments as necessary to avoid this resonance.

92c2fb8fa5 platform/x86/amd/pmc: Move PMC driver to separate directory
With latest commits having PMC code spread across multiple files, it would
be easier to maintain them in a separate directory under amd/pmc.

e8ef8dd28c platform/x86: Move s2idle quirk from thinkpad-acpi to amd-pmc
It turns out that some-non Lenovo systems can benefit from the quirk
introduced for Lenovo systems in commit 455cd867b8 ("platform/x86:
thinkpad_acpi: Add a s2idle resume quirk for a number of laptops").

So move this quirk into running from the amd-pmc driver instead.
No intended functional changes.

da5ce22df5 platform/x86/amd/pmf: Add support for PMF core layer
PMF core layer is meant to abstract the common functionalities
across PMF features. This layer also does the plumbing work
like setting up the mailbox channel for the communication
between the PMF driver and the PMFW (Power Management Firmware)
running on the SMU.

ef233eafe5 platform/x86: Move AMD platform drivers to separate directory
Currently, AMD supported platform drivers are grouped under generic "x86"
folder structure. Move the current drivers (amd-pmc and amd_hsmp) to a
separate directory. This would also mean the newer driver submissions to
pdx86 subsystem in the future will also land in AMD specific directory.
