The interface of GEM SHMEM helpers inconsistently uses either struct drm_gem_object or drm_gem_shmem_object for the GEM object. Convert GEM SHMEM functions to accept struct drm_gem_shmem_object, provide small wrappers for GEM object callbacks and update all users.
Converting all GEM object functions to use drm_gem_shmem_object enables type checking by the C compiler. Previous callers could have passed any implementation of drm_gem_object to the GEM SHMEM helpers. It also removes upcasting in the GEM functions and simplifies the caller side. No functional changes.
For GEM object callbacks, the SHMEM helper library now provides a number of small wrappers that do the necessary upcasting. Again no functional changes.
