[PATCH 1/3] usb: host: xhci-plat: add xhci_plat_start()

[PATCH 1/3] usb: host: xhci-plat: add xhci_plat_start()

[Yoshihiro Shimoda]

Some platforms (such as the Renesas R-Car) need to initialize some specific
registers after xhci driver calls usb_add_hcd() and before the driver calls
xhci_run(). So, this patch adds the xhci_plat_start() function.
