Systems based on Alder Lake P see significant boot time delay if boot firmware tries to control usb ports in unexpected link states. This is seen with self-powered usb devices that survive in U3 link suspended state over S5. A more generic solution to power off ports at shutdown was attempted in commit 83810f84 ("xhci: turn off port power in shutdown") but it caused regression. Add host specific XHCI_RESET_TO_DEFAULT quirk which will reset host and ports back to default state in shutdown.
