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.
