In the Voltage Thermal Management Module(VTM), K3 AM654 supplies a voltage reference and a temperature sensor feature that are gathered in the band gap voltage and temperature sensor (VBGAPTS) module. The band gap provides current and voltage reference for its internal circuits and other analog IP blocks. The analog-to-digital converter (ADC) produces an output value that is proportional to the silicon temperature. Add support for bandgap sensors. Currently reading temperatures and trend computing is supported. Changes in v2: * Fixed yaml errors * renamed am654-industrial-thermal.dtsi to k3-am654-industrial-thermal.dtsi to follow the convention for k3 family.
