volteer: Configure additional unused signals
Configure additional unused signals to save power on S0ix. Savings are
about 200 uW.
EC power consumption, averaged over 60 minutes:
Before changes: Avg 5.07 mW, max 13.61 mW, min 3.68 mW
With changes: Avg 4.84 mW, max 7.14 mW, min 3.54 mW
BUG=b:155882590
BRANCH=none
TEST=make buildall
TEST=Use Volteer reworked with sweetberry and measure power.
