storm: supply vboot GPIO settings in coreboot table
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 Change-Id: I248b90ee06d226a223b6fc0993f209acdd58c77d Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: d48d1dcc88df0c1bd4c50f14dd2e7cd1dd4fba5d Original-Change-Id: Icb7fb55949fa97ead9d19f0da76392ee63bbb5b8 Original-Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Original-Reviewed-on: https://chromium-review.googlesource.com/210922 Reviewed-on: http://review.coreboot.org/9117 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
