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 the global header file containing
'struct rcar_phy_platform_data' consisting of the various bit fields describing
USB ports' pin configuration.

Changes since version 6:
- renamed the header file into <linux/platform_data/usb-rcar-phy.h>, renamed the
guarding #define accordingly;
- rephrased the changelog.
Changes since version 3:
- moved USBPCTRL0 register bit #define's to patch #9;
- replaced USBPCTRL0 register value in the platform data structure by a set of
bit fields describing the configuration of the board, rewrote changelog;
Changes since version 2:
- added #include <linux/types.h>;
- added ACKs from Simon Horman and Kuninori Morimoto.
