drm/i915: Introduce intel_connector_hpd_pin()

Browse source

Simplify the hotplug code connector->encoder->hpd_pin handling
by introducing a helper for exactly this purpose.

In the helper we can neatly deal with the potential lack of an
attached encoder on fresh MST connectors leaving the rest of the
hpd code oblivious to such details.
