drm/i915: Add intel_digital_port lock/unlock hooks
Add hooks to intel_digital_port to lock and unlock the port and add a
helper to check the connector's detect status while the port is locked
already. This simplifies checking the connector detect status in
intel_dp_aux_xfer() and intel_digital_port_connected() in the next two
patches aborting AUX transfers on all DP connectors (except eDP) and
filtering HPD glitches.
