Support write protect GPIO on pit
Daisy doesn't have a write protect signal, so emulate it as a fake
signal which is always low; this maintains the current behavior on
daisy.
BUG=chrome-os-partner:15613
BRANCH=none
TEST=flashinfo shows gpio not asserted
then short across the WP screw and flashinfo shows it asserted
