drm: Add an HPD poll helper to reschedule the poll work

Browse source

commit a94e7ccfc4 upstream.

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.
