During init_connector set the edid, then edid will be set/unset only during
hotplug. For the sake of older platforms where HPD is not stable, let edid
read happen from detect as well only if it is forced to do so.
v2: Removing the 'force' check, instead let detect call read the edid for
platforms older than gen 7 (Shashank)
