gru: kevin: define GPIOs used on both platforms 

The same GPIOs are used on both platforms, definitions are added an a
new .h to make it easier to re-use them across the code.

BRANCH=none
BUG=chrome-os-partner:51537
TEST=panel backlight still enabled on Gru as before. The rest of the
     GPIOs are used in the upcoming patches.
