drm: Create a driver hook for allocating GEM object structs.
The CMA helpers had no way for a driver to extend the struct with its
own fields. Since the CMA helpers are mostly "Allocate a
drm_gem_cma_object, then fill in a few fields", it's hard to write as
pure helpers without passing in a driver callback for the allocate
step.
