drm/amdgpu: add amdgpu_discovery_get_mem_reserved_info_table

Browse source

Add interface to query the optional MEM_RESERVED_INFO table:

  - introduce amdgpu_discovery_get_mem_reserved_info_table() which
    resolves the table from the discovery binary and caches the pointer
    in adev->discovery.mem_reserved_table so subsequent lookups are
    cheap;
  - invoke it once at init time. Missing/invalid table is non-fatal.
