mb/google/zork: Add timestamps around forced delay

Due to a hardware design change, early boards need an additional delay
when initializing the fingerprint sensor.  Add a timestamp around the
delay so it can be subtracted from the timestamp calculation if desired.

BUG=b:171837716
TEST=Look at new timestamp data
