[PATCH] cpufreq: remove setting of policy->cpu in policy->cpus during init

[Sudeep Holla <sudeep.holla@arm.com>]

policy->cpu is copied into policy->cpus in cpufreq_online() before
calling into cpufreq_driver->init(). So there's no need to set the
same in the individual driver init() functions again.

This patch removes the redundant setting of policy->cpu in policy->cpus
in intel_pstate and cppc drivers.

Hi Viresh,

I had copied the cpumask_set_cpu from one of these drivers and when you
pointed out I thought it's better to remove the reference too. Let me
know if it makes sense.

Regards,
Sudeep
