drm/amdgpu: add MCA smu cache support
v1:
because SMU CE valid mca bank will be cleared after reading,
this patch adds mca cache at the driver level to ensure that the mca bank is not lost.
v2:
refine amdgpu_mca_init/fini/reset() function name.
v3:
add mca_cache.lock support
only add CE bank to mca bank cache.
