[PATCH v3 01/22] drm/amdgpu: Introduce GEM object functions



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.

v3:
        * remove amdgpu_object.c from patch (Christian)
v2:
        * move object-function instance to amdgpu_gem.c (Christian)
        * set callbacks in amdgpu_gem_object_create() (Christian)
