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
