[PATCH] drm/vc4: Initialize vc4_drm_driver with CMA helper defaults

[Thomas Zimmermann <tzimmermann@suse.de>]

The function vc4_prime_import_sg_table() is an otherwise empty wrapper
around CMA's drm_gem_cma_prime_import_sg_table(). Removing it in favor
of the latter allows to initialize vc4_drm_driver with CMA's initializer
macro.
