[PATCH v2 3/3] ARM64: dts: mt8173: Add CPU OPP, clock and regulator supply properties

[pi-cheng.chen@linaro.org (Pi-Cheng Chen)]

Add operating-points-v2, clock, and regulator supply properties
required by mt8173-cpufreq driver to enable it.

Signed-off-by: Pi-Cheng Chen <pi-cheng.chen@linaro.org>
---
This patch is based on the patch[1] that adds underlying clock MUX for
MT8173 which is needed by mt8173-cpufreq driver but not yet picked.
