Subject: [PATCH v1] cpufreq: mediatek-hw: Add support for Mediatek cpufreq HW driver

The CPUfreq HW present in some Mediatek chipsets offloads
the steps necessary for changing the frequency of CPUs.
The driver implements the cpufreq driver interface for
this hardware engine. 

This patch depends on the MT6779 DTS patch submitted by Hanks Chen
