thunderbolt: Use wake on connect and disconnect over suspend

Wake on connect is useful for being able to wake up a suspended
laptop without opening the lid by plugging into a dock.

Add the default policy to the USB4 router when wakeup is enabled
for the router.  Behavior for individual ports can be controlled
by port wakeup settings.
