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.

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.

platform/x86: hfi: Introduce AMD Hardware Feedback Interface Driver The AMD Heterogeneous core design and Hardware Feedback Interface (HFI) provide behavioral classification and a dynamically updated ranking table for the scheduler to use when choosing cores for tasks. There are two CPU core types defined: Classic and Dense. Classic cores are the standard performance cores, while Dense cores are optimized for area and efficiency. Heterogeneous compute refers to CPU implementations that are comprised of more than one architectural class, each with two capabilities. This means each CPU reports two separate capabilities: "perf" and "eff". Each capability lists all core ranking numbers between 0 and 255, where a higher number represents a higher capability. Heterogeneous systems can also extend to more than two architectural classes. The purpose of the scheduling feedback mechanism is to provide information to the operating system scheduler in real time, allowing the scheduler to direct threads to the optimal core during task scheduling. All core ranking data are provided by the PMFW via a shared memory ranking table, which the driver reads and uses to update core capabilities to the scheduler. When the hardware updates the table, it generates a platform interrupt to notify the OS to read the new ranking table.
