GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in radeon.

Same comment as for amdgpu, please put that into radeon_gem.c instead.

There's no good header file to put the declarations, right? I'm asking
because checkpatch warns about declarations in the source files.

Yes, that is kind of a mess because radeon used to support both KMS and UMS.

Thanks for cleaning this up,
