thunderbolt: Explicitly enable lane adapter hotplug events at startup
Software that has run before the USB4 CM in Linux runs may have disabled
hotplug events for a given lane adapter.
Other CMs such as that one distributed with Windows 11 will enable hotplug
events. Do the same thing in the Linux CM which fixes hotplug events on
"AMD Pink Sardine".
