drm/vc4: drv: Call component_unbind_all()
While we were using the component framework to deal with all the DRM
subdevices, we were not calling component_unbind_all().
This leads to none of the subdevices freeing up their resources as part of
their unbind() or device managed hooks.
Fixes: c8b75bca92cb ("drm/vc4: Add KMS support for Raspberry Pi.")
