flash_ec: Accomodate using flashrom on beaglebone

Browse Source 
Currently, using flash_ec for mec1322 chips only
supports flashing from servo v2.  Updated to work from
v3 as well.  This is a resubmission.

BUG=chromium:554230
BRANCH=None
TEST=tested locally with beaglebone/cyan setup at my desk
     Ran flash_ec --board=cyan --chip=mec1322
     --image=/tmp/image.bin.  Also ran with servov2.
