storm: supply vboot GPIO settings in coreboot table

Browse source 
Storm provides three real and two fake gpios. To keep things simple,
define them all as active low and provide appropriate values for the
fake ones.

BUG=chrome-os-partner:30705
TEST=with the appropriate depthcharge change booted proto0, observed
     appropriate behavior following the dev switch setting
