platform/x86: amd: Use *-y instead of *-objs in Makefiles

The `objs` suffix is reserved for user-space tools. Use the `y` suffix
instead, which is usually used for kernel drivers.

While at it, fix alignment in AMD PMC and PMF Makefiles.

platform/x86/amd: amd_3d_vcache: Add AMD 3D V-Cache optimizer driver

AMD X3D processors, also known as AMD 3D V-Cache, feature dual Core
Complex Dies (CCDs) and enlarged L3 cache, enabling dynamic mode
switching between Frequency and Cache modes. To optimize performance,
implement the AMD 3D V-Cache Optimizer, which allows selecting either:

Frequency mode: cores within the faster CCD are prioritized before
those in the slower CCD.

Cache mode: cores within the larger L3 CCD are prioritized before
those in the smaller L3 CCD.

platform/x86/amd/hsmp: Create separate ACPI, plat and common drivers

Separate the probes for HSMP ACPI and platform device drivers.

Provide a Kconfig option to choose between ACPI or the platform device
based driver. The common code which is the core part of the HSMP driver
maintained at hsmp.c is guarded by AMD_HSMP config and is selected by
these two driver configs. This will be built into separate hsmp_common.ko
module and acpi as hsmp_acpi and plat as amd_hsmp respectively.

Also add "|| COMPILE_TEST" clause in Kconfig to get build coverage for
HSMP.

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.
