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. Co-developed-by:Perry Yuan <perry.yuan@amd.com> Signed-off-by:
