thunderbolt: Add wake from DisplayPort
Latest USB4 spec added a new wake bit for DisplayPort so add this to the driver when runtime suspending. This way wake up the domain when a new monitor is plugged in to any of the device routers. Also do the same for pre-USB4 devices through the link controller registers as documented in chapter 13 of the USB4 spec. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
