This will break bisectability. You need to first add that
"cyppress,firmware-build" identifier without removing the old
"ccgx,firmware-build" identifier, and then introduce a separate
clean-up patch where you remove it when it's safe to remove:

1. Add new - This patch.
2. Modify users - PATCH 7/11.
3. Remove old - *missing*.
