Enabling CONFIG_CPU_V6 there may have noticeable overhead on v7
platforms, and it would be a bit confusing, so I'm not sure about doing
that by itself.

However, a related question would be whether we want to add options
for ARMv7VE (adding IDIV and LPAE) and ARMv8 and then using
config fragments to specialize what is currently the multi_v7_defconfig
to give us four separate configurations (v6/v7/v7ve/v8.0) with an
increasing feature set but decreasing platform support.
