veyron: Adapt to new board revisions
This patch adds support for Pinky rev3 (board ID 2) and Jerry rev2: the power button GPIO changed polarity to low, the 5V_DRV pin for USB power was moved to the AP again (welcome back!), and the EMMC_RST_L is now finally on a port with the right IO voltage so we don't need any weird pull-up tricks anymore. Since there are very few Jerry rev1s around, we'll just move it over to the new code directly without introducing board ID differences (also, because I have no idea how they stuffed it this time... is this one actually called rev2?). BRANCH=None BUG=None TEST=Still boots on my Pinky rev2, though that doesn't say much.
