This patch reworks the mode pin code to keep the pin definitions in one place. The mode pins values are now the value of the bit instead of bit number. With this patch in place the sh7785 header file contains mode pin comments. The sh7785 clock code and the sh7785lcr board code are updated to reflect the new shared mode pins.
