[PATCH v4 0/4] cpufreq: Introduce TI CPUFreq/OPP Driver

This is v4 of the series to introduce the ti-cpufreq driver
which parses SoC data and provides opp-supported-hw data to the
OPP core in order to enable the proper OPPs for the silicon in use.
Based on v4.10-rc4.
This series has two changes from v3:
* Export dev_pm_opp_of_get_opp_desc_node for modules
* Simplify the dt binding by just providing a "syscon" phandle and
letting the driver handle offsets.
* Add a patch to remove the automatic platdev creation for am335x
and dra7 platforms as this driver will now do it. Note that this
will *not* break existing cpufreq implementations on these platforms
as the ti-cpufreq can fall back to opp v1 tables for backwards
DT patches to enable this driver will follow after the DT binding is merged.
Finally, branch for testing, with updated DT nodes, pushed here .
