security/vboot: Use persistent context to read GBB flags

With the persistent vboot context coreboot no longer needs to read GBB
flags from flash itself -- it can just ask vboot for the cached result.
This patch removes the existing GBB code and provides gbb_is_flag_set()
(with a slightly better namespaced name) as a static inline instead.
