cpufreq: drivers: Remove unnecessary assignments of policy-> members

Some assignments of policy-> min/max/cur/cpuinfo.min_freq/cpuinfo.max_freq
aren't required as part of it is done by cpufreq driver or cpufreq core.

Remove them.

At some places we merge multiple lines together too.

For setting some of these values, the frequency table helpers might be
helpful. See the section 2 for more information on them.
For setting some of these values (cpuinfo.min[max]_freq, policy->min[max]), the

SMP systems normally have same clock source for a group of cpus. For these the
.init() would be called only once for the first online cpu. Here the .init()
