Subject: [PATCH v5 1/7] dt-bindings: regulator: Add bindings for MediaTek DVFSRC Regulators

The Dynamic Voltage and Frequency Scaling Resource Collector Regulators
are controlled with votes to the DVFSRC hardware.

This adds support for the regulators found in MT6873, MT8183, MT8192
and MT8195 SoCs.
