Subject: [PATCH] ARM: Remove ARCH_HAS_CPUFREQ config option

This config exists entirely to hide the cpufreq menu from the
kernel configuration unless a platform has selected it. Nothing
is actually built if this config is 'Y' and it just leads to
more patches that add a select under a platform Kconfig so that
some other CPUfreq option can be chosen. Let's remove the
option so that we can always enable CPUfreq drivers on ARM
platforms.
