fsp2_0: implement stage cache for silicon init
Stage cache will save ~20ms on S3 resume for apollolake platforms.
Implementing the cache in ramstage to save silicon init and reload
it on resume. This patch adds passing S3 status to silicon init in
order to verify that the wake is from S3 and not for some other
reason. This patch also includes changes needed for quark and
skylake platforms that require fsp 2.0.
BUG=chrome-os-partner:56941
BRANCH=none
TEST=built for reef and tested boot and S3 resume path saving 20ms
