drm/amdgpu: Change num_xcd to xcc_mask
Instead of number of XCCs, keep a mask of XCCs for the exact XCCs available on the ASIC. XCC configuration could differ based on different ASIC configs. v2: Rename num_xcd to num_xcc (Hawking) Use smaller xcc_mask size, changed to u16 (Le) Signed-off-by: Lijo Lazar <lijo.lazar@amd.com> Reviewed-by: Hawking Zhang <Hawking.Zhang@amd.com> Reviewed-by: Le Ma <Le.Ma@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
