Probe deferral can cause the platform-data we access to be freed already
causing ugly splats on system shutdown.

Fix this via a small component-helper and adapting the rockchip-drm
shutdown handler.

Heiko Stuebner (2):
drivers: base: component: add function to query the bound status
drm/rockchip: Fix shutdown when no drm-device is set up
