veyron_pinky: Add rev2 support, clean up mainboard.c
This patch adds support for the board changes in rev2 (board_id = 0001). It also moves the existing mainboard.c code around a bit to group it by component. BUG=chrome-os-partner:32139 TEST=Booted on rev1. Confirmed SD card still works. Confirmed power button was still as broken as before.
