chromeos: Allow disabling vboot firmware verification when ChromeOS is enabled
Some ChromeOS bindings might be wanted without using vboot verification, for
instance to boot up depthcharge from the version of Coreboot installed in the
write-protected part of the SPI flash (without jumping to a RW firmware).
Vboot firmware verification is still selected by default when ChromeOS is
enabled, but this allows more flexibility since vboot firmware verification is
no longer a hard requirement for ChromeOS (that this particular use case still
allows booting ChromeOS).
In the future, it would make sense to have all the separate components that
CONFIG_CHROMEOS enables have their own config options, so that they can be
enabled separately.
