The suspend operation of VIA xHCI host have some issues and hibernate operation works fine, so The XHCI_RESET_ON_RESUME quirk is added for it. This patch should base on "xHCI: Don't write zeroed pointer to xHC registers" that is released by Sarah. Otherwise, the host system error will ocurr in the hibernate operation process.
