[PATCH v3 00/43] 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.
To address Laurent's comment on the amount of changes per patch, I re-
organized the series.
1) There are now DRIVER_OPS macros for drivers that require a virtual
address on imported buffers, and macros for drivers that don't. Therefore,
drivers don't switch to drm_gem_cma_prime_import_sg_table_vmap()
implicitly when they begin using the DRIVER_OPS macro.
2) I split each driver's patch into two: the first converts the driver to
GEM CMA object functions, the second introduces the DRIVER_OPS macro.
Neither patch should result in a functional change. I kept existing R-b
and A-b tags on both patches. Existing Tested-by tags are only on the
final patch, as that's closest to what has been tested.
3) I dropped the conversion to drm_gem_prime_mmap() from the patchset. As
part of this change, the CMA object functions could provide an mmap
function, which is worth it's own series. The patch for aspeed requires
drm_gem_prime_mmap(), so I removed it from the series.
Patches 1 to 3 update the existing macro and helper to similar naming as with
SHMEM, add a new DRIVER_OPS macro, and add helpers for drivers that override
the default implementation for .dumb_create(). The remaining patches up to
the final one convert the drivers. The kirin driver also changes to the
default dumb_create function. The final patch deletes .gem_print_info from
struct drm_driver.
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.
v3:
* reorganized the series
* split each driver patch into two small ones (Laurent)
* drop the conversion to drm_gem_prime_mmap()
* remove the patch for aspeed
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)
