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

This patchset includes 6 patches and depends on the MT6779 DTS patch[1] submitted by Hanks Chen.
The first 3 patches are for CPUFREQ HW driver and device tree binding, which are already sent before separately [2][3]. For binding part, I add a new patch to add property in cpu schema.
Besides, we add three more patches including EM power table, SVS CPU initialize, and cooling device.
