drm/amdgpu: add vram_type and vram_bit_width for interface query (v2)
Track the type of vram on the board and provide a query for it. User mode drivers and tools want this information for determining bandwidth information and form informational purposes. v2: fix build when CI support is not enabled Signed-off-by: Ken Wang <Qingqing.Wang@amd.com> Reviewed-by: Jammy Zhou <Jammy.Zhou@amd.com>
