soc: mediatek: Add MediaTek DVFS Resource Collector (DVFSRC) driver
The Dynamic Voltage and Frequency Scaling Resource Collector (DVFSRC) is a
Hardware module used to collect all the requests from both software and the
various remote processors embedded into the SoC and decide about a minimum
operating voltage and a minimum DRAM frequency to fulfill those requests in
an effort to provide the best achievable performance per watt.
This hardware IP is capable of transparently performing direct register R/W
on all of the DVFSRC-controlled regulators and SoC bandwidth knobs.
This driver includes support for MT8183, MT8192 and MT8195.
