GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in amdgpu. The only exception is gem_prime_mmap,
which is non-trivial to convert.
v2:
* move object-function instance to amdgpu_gem.c (Christian)
* set callbacks in amdgpu_gem_object_create() (Christian)
