CHROMIUM: drm/rockchip/analogix_dp: Wire the shutdown callback to disable PSR

We have to disable PSR before shutdown to avoid any asynchronous PSR
code to interfere with Rockchip DRM device shutdown. We use the recently
added analogix_dp_shutdown() function and rockchip_dp_cleanup() we
already use for unregistering PSR at unbind time.
