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.
