[PATCH 11/14] ARM: v6k: use CPU domain feature if we include support for arch < ARMv6K

[Russell King - ARM Linux <linux@arm.linux.org.uk>]

Rather than turning off CPU domain switching when the build architecture
includes ARMv6K, thereby causing problems for ARMv6-supporting kernels,
turn it on when it's required to support a CPU architecture.
