google/veyron_rialto: support the developer key GPIO
Currently (EVT) this is a pullup resistor on the board (i.e. always in
dev mode). Future builds it will be pull down and require servo or HW
modification to control. Either way, this change means the FW should
acknowledge it.
BUG=chrome-os-partner:38663
TEST=Manually verified that servo devmode switch toggles this GPIO. requires FW signing to verify GPIO is observed and dev mode active.
BRANCH=none
