drm/omap: dss: Merge two disconnection helpers
To simplify the pipeline disconnection handling merge the omapdss_device_disconnect() and omapdss_output_unset_device() functions. The device state check is now called for every device in the pipeline, extending this sanity check coverage. There is no need to return an error from omapdss_device_disconnect() when the check fails, as omapdss_output_unset_device() used to do, given that we can't prevent disconnection due to device unbinding (the return value of omapdss_output_unset_device() is never checked in the current code for that reason).
