drm/amdkfd: Fix the warning of array-index-out-of-bounds

For some GPUs with more CUs, the original sibling_map[32]
in struct crat_subtype_cache is not enough
to save the cache information when create the VCRAT table,
so skip filling the struct crat_subtype_cache info instead
fill struct kfd_cache_properties directly to fix this problem.
