I'm proposing a small policy change for the way we refer to boolean Kconfig variables in code. Right now, the directive is to always use the IS_ENABLED() macro. I would like to replace this with a shorter macro CONFIG() that also removes the need to type the CONFIG_ prefix again. The idea is mostly to save some horizontal space and the occasional extra line break for this boilerplate and make it a little easier to type.

It's a very simple change (patch train starts at https://review.coreboot.org/c/coreboot/+/31773), but since it affects pretty much all code in coreboot and payloads I wanted to send out a quick FYI. Please let me know if anyone has any concerns with this.
