[Intel-gfx] [PATCH 01/24] drm/armada: Use devm_drm_dev_alloc

Also remove the now no longer needed build bug on since that's already
not needed anymore with drmm_add_final_kfree. Conversion to managed
drm_device cleanup is easy, the final drm_dev_put() is already the
last thing in both the bind unbind as in the unbind flow.
Also, this relies on component.c correctly wrapping bind&unbind in
separate devres groups, which it does.
