drm: Add an HPD poll helper to reschedule the poll work
Add a helper to reschedule drm_mode_config::output_poll_work after
polling has been enabled for a connector (and needing a reschedule,
since previously polling was disabled for all connectors and hence
output_poll_work was not running).
This is needed by the next patch fixing HPD polling on i915.
