-Amazon's Annapurna Labs Thermal Sensor

-Simple thermal device that allows temperature reading by a single MMIO

-Required properties:
-- compatible: "amazon,al-thermal".
-- reg: The physical base address and length of the sensor's registers.
-- #thermal-sensor-cells: Must be 1. See Documentation/devicetree/bindings/thermal/thermal-sensor.yaml for a description.
