drm/amdgpu: query aldebaran gfx_config through atomfirmware i/f
For ASICs that don't support ip discovery feature, query gfx configuration through atomfirmware interface, rather than gpu_info firmware. Signed-off-by: Hawking Zhang <Hawking.Zhang@amd.com> Reviewed-by: Feifei Xu <Feifei.Xu@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
