Howard Yen ea9acb155e FROMLIST: usb: xhci-plat: add xhci_plat_priv_overwrite
Add an overwrite to platform specific callback for setting up the
xhci_vendor_ops, allow vendor to store the xhci_vendor_ops and
overwrite them when xhci_plat_probe invoked.

This change is depend on Commit in this patch series
("usb: host: add xhci hooks for USB offload"), vendor needs
to invoke xhci_plat_register_vendor_ops() to register the vendor specific
vendor_ops. And the vendor_ops will overwrite the vendor_ops inside
xhci_plat_priv in xhci_vendor_init() during xhci-plat-hcd probe.
