soc/intel/apollolake: Implement stage cache to improve resume time
This patch enables stage cache to save ~40ms during S3 resume.
It saves ramstage in the stage cache and restores it on resume
so that ramstage does not have to reinitialize during the
resume flow. Stage cache functionality is added to postcar stage
since ramstage is called from postcar.
BUG=chrome-os-partner:56941
BRANCH=none
TEST=built for Reef and tested ramstage being cached
