The resume operation of Phytium Px210 xHCI host would failed
to restore state. Use the XHCI_RESET_ON_RESUME quirk to skip
it and reset the controller after resume.

Changlog:
 *v1 -> v2: Move the PCI_VENDOR_ID_PHYTIUM form pci_ids.h to xhci-pci.c
  v2 -> v3: Change "||" to "&&", that was a mistake.
