drm/vram: Set GEM object functions for PRIME
PRIME functionality is now provided via the callback functions in
struct drm_gem_object_funcs. The driver-structure functions are obsolete.
As a side effect of this patch, VRAM-based drivers get basic PRIME
support automatically without having to set any flags or additional
fields.
v2:
- use existing PRIME functions for object's table
v3:
- move object table to EOF so it can refer to internal interfaces
