This makes sense, because Thumb-2 code can't execute on plain ARMv6 processors. This will avoid accidentally configuring a broken kernel where the config otherwise would allow multiple architecture versions to coexist in the same kernel. Not adding !CPU_V5 etc., because the chance of anyone trying to put v5 and v7 in the same kernel is low, and I'm not aware of any mach which can do this. These could be added later if it matters. Note that the rules may need to be refined if support for the ARM1156J(F)-S processor is later added to the kernel, since this processor supports the rare ARMv6T2 extensions, which add support for Thumb-2 and a few other ARMv7 features.
