hatch: Create faffy variant

Create the faffy variant of the puff reference board by copying
the template files to a new directory named for the variant.

(Auto-Generated by create_coreboot_variant.sh version 4.1.1).

V.2: Manually modified to keep Kconfig sorted.

BUG=b:157448038
BRANCH=None
TEST=util/abuild/abuild -p none -t google/hatch -x -a
make sure the build includes GOOGLE_FAFFY
