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.

Changes since version 2:
- added #include <linux/types.h>;
- added ACKs from Simon Horman and Kuninori Morimoto.
