Subject: Re: [RFT PATCH v2 2/3] ARM: Fix *MIGHT_HAVE_PCI* config from being selected redundantly

If that's the purpose, then CM-X255 and CM-X270 don't fall in that category, as
they are not part of ARCH_MULTIPLATFORM nor ready for it AFAIK. So the change
below shouldn't be done according to the commit message.
