Aaron Durbin c64627689b rambi: fix write-protect gpio reading at romstage
On rambi there is an external 10K pull up while the hardware
resets GPIO_SUS[06]'s config to 20K pull down. These pulls
are fighting creating a voltage that when read as a digital
value is incorrect. Rectify this by disabling the intnernal
pull down.

BUG=chrome-os-partner:25641
BRANCH=baytrail
TEST=Built and booted. crossystem wpsw_boot is now correct.
