veyron_pinky: Add board ID support

This patch adds code to read the board ID from Pinky and put it into the
coreboot table.

(Note: This implementation differs slightly from Tegra since it pinmuxes
the GPIOs inside board_id(). That means the pinmuxing might be set more
than once if called in multiple stages, which is perfectly harmless and
in my opinion cleaner than having to (remember to) do it manually in one
of the per-stage files.)

BUG=chrome-os-partner:30167
TEST=With depthcharge patch, select -rev1 device tree for board ID 0.
