pit: Replace the snow GPIO indexes with ones for pit.

Browse source 
The GPIOs used by vboot and setting up the display and backlight were still
the ones for snow. This change updates them so they're correct for pit.

BUG=chrome-os-partner:19420
TEST=Built and booted to when the payload is loaded on pit
BRANCH=None
