Ok, I mentioned that as the other option but was not sure which one
was more suitable since CHROME_PLATFORMS is a category and the
individual drivers already depend on a given arch. But I will make it
depends on X86 || ARM again plus || COMPILE_TEST and in the future if
there is a Chromebook on !X86 and !ARM, that new arch can be added to
the or logic.

Yes, I think this is the real issue. I added the select instead of a
depends to avoid breaking git bisection when moving the cros_ec com
helpers out of MFD since some platforms use MFD_CROS_EC but don't
enable CHROME_PLATFORMS on their defconfigs. But I'll change the
select to depends instead and include the defconfig changes as a
dependency in the series to avoid breaking git bisection.
