[Intel-gfx] [FOR CI 13/22] drm/vc4: Use drm_atomic_helper_shutdown

[Daniel Vetter]

drm_plane_helper_disable is a non-atomic drivers only function, and
will blow up (since no one passes the locking context it needs).

Atomic drivers which want to quiescent their hw on unload should
use drm_atomic_helper_shutdown() instead.

v2: Rebase.
