[PATCH] cpufreq: enable ARM drivers on arm64

[Mark Brown]

From: Rob Herring <rob.herring@calxeda.com>

Enable cpufreq and power kconfig menus on arm64 along with arm cpufreq
drivers. The power menu is needed for OPP support. At least on Calxeda
systems, the same cpufreq driver is used for arm and arm64 based
systems.

Is this patch based on recent kernels ? If so, either it should have caused
conflicts or silently duplicated the entries. "Power management options" are
already present.

Also to be more consistent it with menu options, I would prefer this to be
placed under "CPU Power Management" like CPUIdle.

Regards,
Sudeep

Yes, it was against -next.  It looks like either the original patch had
the duplication or it crept in there during the rather lengthy time
between submission and acceptance.

I'll submit an incremental patch for this; in general the best thing to
do once things have been applied is to send a patch.
