Mathias Nyman c3bbacd61b xhci: disable U3 suspended ports in S4 hibernate poweroff_late stage
Disable U3 suspended ports in hibernate S4 poweroff_late for systems
with XHCI_RESET_TO_DEFAULT quirk, if wakeup is not enabled.

This reduces the number of self-powered usb devices from surviving in
U3 suspended state into next reboot.

Bootloader/firmware on these systems can't handle usb ports in U3, and
will timeout, causing extra delay during reboot/restore from S4.

Add pci_poweroff_late() callback to struct usb_hcd to get this done at
the correct stage in hibernate.
