Subject: drm/cma-helper: Rework DRM_GEM_CMA_VMAP_DRIVER_OPS macro
Git-commit: 06d6620164b2989468cd4ea809645e6483623314
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

Rename the macro to DRM_GEM_CMA_DRIVER_OPS_VMAP to align naming with
SHMEM helpers and drm_gem_cma_prime_import_sg_table_vmap(). An variant of
the macro is provided for drivers that override the default .dumb_create
callback. Adapt drivers to the changes.

v3:
	* rename macro to signal implicit vmap on imported buffers
v2:
	* provide DRM_GEM_CMA_DRIVER_OPS_WITH_DUMB_CREATE
