hatch: automate creating a new variant in coreboot
To create a new variant of the hatch baseboard, we need to add the variant's GBB_HWID and other information to Kconfig and Kconfig.name, and set up a skeletal build based on the hatch baseboard.
BUG=b:140261109 BRANCH=none TEST=``./create_coreboot_variant.sh sushi && git show`` Kconfig will have three new lines for the SUSHI variant, and Kconfig.name will have an entirely new section. New files created are: variants/sushi/Makefile.inc variants/sushi/overridetree.cb variants/sushi/include/ec.h variants/sushi/include/gpio.h variants/sushi/include/variant/acpi/dptf.asl
Also run the script with an existing board name to verify that you can't create a variant that already exists.
