Document the bindings for the Thermal Management Unit (TMU) System Controller found on Google GS101 SoCs. This memory-mapped block exposes the registers required for reading thermal interrupt status bits. It functions as a syscon provider, allowing the main thermal driver to access these registers while the firmware manages the core thermal logic.
