drm/gm12u320: More drmm_
The drm_mode_config_cleanup call we can drop, and all the allocations
we can switch over to drmm_kzalloc. Unfortunately the work queue is
still present, so can't get rid of the drm_driver->release function
outright.
v2: Use drmm_mode_config_init() for more clarity (Sam, Thomas)
