[Intel-gfx] [PATCH v5 1/2] drm: Add detection of changing of edid on between suspend and resume

The hotplug detection routine of drm_helper_hpd_irq_event() can detect changing of status of connector, but it can not detect changing of edid. Following scenario requires detection of changing of edid. 1) plug display device to a connector 2) system suspend 3) unplug 1)'s display device and
