Override the PMIC-default voltage constraints for VGPU and VSRAM_GPU
with the platform specific vmin/vmax for the highest possible SoC
binning.
The maximum voltage numbers don't match the existing OPP table though.
The OPP table that we've got in mt8183.dtsi does not declare frequencies for the
highest binning for this SoC, I guess because there was no way to check fuses to
restrict the table to bin XYZ.
These maximum voltages are - true - higher compared to the highest voltage in
the GPU OPP table, but they're still in spec (check datasheets!).
Should I reword the commit description?

Angelo
