drm/ingenic: Call drm_atomic_helper_shutdown() at shutdown time
Based on grepping through the source code this driver appears to be
missing a call to drm_atomic_helper_shutdown() at system shutdown
time. Among other things, this means that if a panel is in use that it
won't be cleanly powered off at system shutdown time.
The fact that we should call drm_atomic_helper_shutdown() in the case
of OS shutdown/restart comes straight out of the kernel doc "driver
instance overview" in drm_drv.c.
Since this driver uses the component model and shutdown happens at the
base driver, we communicate whether we have to call
drm_atomic_helper_shutdown() by seeing if drvdata is non-NULL.
