google/chromeec: implement vboot_(save|retrieve)_hash API
For x86 systems which resume through the reset vector one needs to ensure the the RW slot taken at resume time matches the one at boot time. To that end, allow Chrome OS EC to supply the plumbing to vboot for storing and retrieving the RW slots' hash digest using the vstore backend. BUG=chrome-os-partner:46049 BRANCH=glados TEST=Suspended and resumed on chell. Also, tested with an EC build which returns a bad hash to ensure that is properly caught.
