vendorcode/google/chromeos: Fill in firmware ID regions

Chrome OS images have three firmware ID regions, to store version
information for the read-only and the two read-write areas. Fill them
with a suitable default and allow configuring a different scheme.

There's already an override in google/foster and google/rotor to match
the naming scheme used so far (in depthcharge).

BUG=chromium:595715
BRANCH=none
TEST=/build/$board/firmware/coreboot.rom has the expected values in the
regions.
