[PATCH v2 00/23] drm: Convert most CMA-based drivers to GEM object functions

Most of the CMA-based drivers use the default implementation for the
callbacks in struct drm_driver. With this patch, these interfaces are
initialized with a common helper macro and GEM object functions replace
several deprecated interfaces.

The first patch updates the existing macro to similar naming as with
SHMEM and adds a helper for drivers that override the default implementation
for .dumb_create(). The remaining patches convert the drivers. The aspeed
driver already uses GEM object functions and only changes to the initializer
macro. The kirin driver also changes to the default dumb_create function.

I don't have much of the hardware, so it's only compile-tested on aarch64,
arm and x86-64 only. Several patches have Tested-by tags. The aspeed driver
has used the implemented scheme for a while.

v2:
	* add more detailed commit messages (Laurent, Sam)
	* use default .dumb_create implementation in kirin (Emil)
	* fix zte build error (Sam, Emil)
	* introduce DRM_GEM_CMA_DRIVER_OPS_WITH_DUMB_CREATE (everyone)
