If we centralize the MODULE_FIRMWARE() requests I think we should rather
move that to amdgpu_ucode.c instead.
One minor problem is that we considered adding support for disabling
some hw generations during compilation, but since this never
materialized we are probably never going to need it.
With the MODULE_FIRMWARE() requests moved feel free to add an Acked-by:
