Please prefix patches to follow the sybsystem style. For Thunderbolt it
should be "thunderbolt: ....".

This will cause any monitor plug to wake up the system and I'm not sure
we want that, at least to be default behaviour. If you have a regular
Type-C (non-USB4/TBT) dock and you plug in a monitor to that, does it
wake up?

IIRC I already suggested you to do this for the USB4 ports themselves
(struct usb4_port) so that userspace can make them wake up the system on
any event by writing "enabled > .../wakeup" which is the normal way.
