thunderbolt: Avoid notify PM core about runtime PM resume
Currently we notify PM core about occurred wakes after any resume. This
is not actually needed after resume from runtime suspend. Hence, notify
PM core about occurred wakes only after resume from system sleep. Also,
if the wake occurred in USB4 router upstream port, we don't notify the
PM core about it since it is not actually needed and can cause
unexpected autowake (e.g. if /sys/power/wakeup_count is used).
While there add the missing kernel-doc for tb_switch_resume().
