drm/i915: disable hotplug detect before Ironlake CRT detect

commit eceb784cec4dc0fcc2993d9ee4a7c0d111ada80a upstream.

This tries to fix CRT detect loop hang seen on some Ironlake form
factor, to clear up hotplug detect state before taking CRT detect
to make sure next hotplug detect cycle is consistent.
