Magnus Damm 0d4fdbb64f sh: rework mode pin code
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.
