drm/shmem-helper: Export dedicated wrappers for GEM object functions

Browse Source 
Wrap GEM SHMEM functions for struct drm_gem_object_funcs and update
all callers. This will allow for an update of the public interfaces
of the GEM SHMEM helper library.

v2:
	* fix docs for drm_gem_shmem_object_print_info()
