David Hendricks 21db62eb0e gpio: add a function to read GPIO array as base-2 value ...

This adds gpio_base2_value() which reads an array of 2-state
GPIOs and returns a base-2 value, where gpio[0] represents the
least significant bit.

BUG=none
BRANCH=none
TEST=tested with follow-up patches for pinky
