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.
