Currently the driver hard-codes USBPCTRL0 register to 0.  It is wrong since this
register contains board-specific USB ports configuration and so its value should
be somehow passed via the platform data.  Add <linux/usb/rcar-phy.h> file with
the USBPCTRL0 bit #define's and 'struct rcar_phy_platform_data' containing the
value to be set by the driver to that register.
