All .enable() and .disable() handlers for panels and connectors share
common code that validates and updates the device's state. Move it to
common locations in the omap_encoder_enable() and omap_encoder_disable()
handlers.
The enabled check in the .disable() handler is left untouched, it will
be addressed separately.
