pinctrl: sirf: add USB1/UART1 pinmux usb/uart share 

dn and dp of USB1 can share with UART1(UART1 can route rx,tx to dn and dp pins of USB1).
here we add this pinmux capability.
USB1/UART1 mode selection has dedicated control register in RSC module, here we attach
the register offset of private data of related pin groups.
