drm/amdgpu: rework IP block registration (v2)
This makes it easier to replace specific IP blocks on asics for handling virtual_dce, DAL, etc. and for building IP lists for hw or tables. This also stored the status information in the same structure. v2: split out spelling fix into a separate patch add a function to add IPs to the list Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
