drm/imx: Use GEM CMA object functions

Create GEM objects with drm_gem_cma_create_object_default_funcs(), which
allocates the object and sets CMA's default object functions. Corresponding
callbacks in struct drm_driver are cleared. No functional changes are made.

Driver and object-function instances use the same callback functions, with
the exception of vunmap. The implementation of vunmap is empty and left out
in CMA's default object functions.

v3:
	* convert to DRIVER_OPS macro in a separate patch
