sh: add r8a66597 usb0 host to the se7724 board 



Add USB host support for port CN27 on the Solution Engine 7724
board. The r8a66597-hcd driver is hooked up as a platform device
and some registers are configured to enable the USB host function.
The hardware driving the USB port is the on-chip USB0 block in
the sh7724 processor configured as USB host controller.
