baytrail: snapshot power state in romstage
The memory reference code doesn't maintain some of the registers which contain valuable information in order to log correct reset and wake events in the eventlog. Therefore snapshot the registers which matter in this area so that they can be consumed by ramstage. BUG=chrome-os-partner:24907 BRANCH=rambi,squawks TEST=Did various resets/wakes with logging patch which consumes this structure. Eventlog can pick up reset events and power failures.
