arm64: dts: mediatek: mt8186: Wire up GPU voltage/frequency scaling
Add the GPU's OPP table. This is from the downstream ChromeOS kernel, adapted to the new upstream opp-supported-hw binning format. Also add dynamic-power-coefficient for the GPU. Also add label for mfg1 power domain. This is to be used at the board level to add a regulator supply for the power domain.
