Subject: [PATCH 0/5] CPUFreq: Initialize CPU's OPP tables from core

All drivers expecting CPU's OPPs from device tree initialize OPP table using
of_init_opp_table() and there is nothing driver specific in that. They all do it
in the same way adding to code redundancy.

It would be better if we can get rid of code redundancy by initializing CPU OPPs
from core code for all CPUs that have a "operating-points" property defined in
their node.

First patch initializes OPPs as soon as CPU device is registered in
register_cpu(). Following patches get rid of these calls from individual drivers
which are currently initializing OPPs.

The idea was initially discussed here: https://lkml.org/lkml/2014/5/17/123
