Duncan Laurie 81efb83e95 ec: Add temporary secure storage for the host during boot ...

This adds a temporary secure storage interface for the EC to be able
to store small amounts of data from the host that is locked until the
chipset resets.  This is used by pre-memory verified boot on x86 systems
where we need to know which RW slot to boot and what the hash is to
ensure that we can resume from S3 safely.
