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