[PATCH 2/3] thermal: Add Mediatek thermal controller support

This adds support for the Mediatek thermal controller found on MT8173 and likely other SoCs. The controller is a bit special. It does not have its own ADC, instead it controls the on-SoC AUXADC via AHB bus accesses. For this reason we need the physical address of the AUXADC. Also it controls a mux
