Re-enable call to intel_hpd_poll_init() in vlv_display_power_well_deinit().
Allows valleyview and cherryview machines to boot without a display connected.
Previously they would get flooded by HPD events. HPD is known to not work on
valleyview and cherryview when powerwells are shut off.
Reported by jan@ on tech@ with valleyview and km at krot.org on bugs@ with
cherryview.
