drm/omap: Move HPD disconnection handling to omap_connector
On HDMI outputs, CEC support requires notification of HPD signal
deassertion. The HPD signal can be handled by various omap_dss_device
instances in the pipeline, and all of them forward HPD events to the
OMAP4 internal HDMI encoder.
Knowledge of the DSS internals need to be removed from the
omap_dss_device instances in order to migrate to drm_bridge. To do so,
move HPD handling for CEC to the omap_connector.
