cros: Inform U-Boot via fake gpio when VGA Option ROM is loaded
This prepares the way for vboot to inform coreboot when it needs the VGA
Option ROM loaded. Coreboot can't always know when it's needed (with
keyboard-based dev-mode, coreboot can't tell if we're in dev-mode or not).
By the time we get to U-Boot, it's too late, so we need two extra bits - one
for vboot to tell coreboot to load the Option ROM and another for coreboot
to let vboot know it's been done.
This change sets up the communication, but doesn't act on it just yet.
Even with this CL we always load the VGA Option ROM, so there's nothing to
test. There should be no user-visible change.
