drm/mediatek: Use drm_atomic_helper_wait_for_fences

If we use the gem fb helper as the prepare_fb hook, plus the
drm_prime.c import helpers now automatically setting obj->resv, we can
use the shared helpers to wait for fences instead of rolling our own.
Note that this relies on mtk setting drm_fb->obj, which is already
done in mtk_drm_framebuffer_init().

Aside: Probably can use the default commit_tail with this again, but I
didn't check for that.
