v1: Pin 7 should be IO

Pin 7 is a general purpose IO pin. v1 PCB treats it like a supply pin with power and a capacitor. This won't cause a problem in normal use. The CoolRunner-II board was made first and has a secondary power supply pin there, it was probably a mistake when we hacked the CoolRunnerII board to work with the XC9572XL.

A v1a fix is on the way, but it will not be in production until the third batch of CPLD breakouts.
