True, but lets fix it.  Ideally, we would have something to select
"ARMV7", but we don't yet, and I won't make that your pre-req.  All of
the above options are only used by sunxi and arndale and vexpress right
now.  Add arch/arm/cpu/armv7/Kconfig for the above ARMv7 options, source
it from arch/arm/Kconfig and make the contents be on if ARNDALE || CA15
|| SUNXI with a comment on needing to clean this up further once we have
more fine-grained selects on SoC features.
