Since the BCM2711 doesn't have a AVS TMON block, the thermal information
must be retrieved from the AVS ring oscillator block. So add a new
suitable binding.

+Binding for Thermal Sensor driver for BCM2711 SoCs.
+
+Required properties:
+- compatible: must be: "brcm,bcm2711-thermal"
+- reg: Address range of the thermal registers.
+- clocks: Phandle of the clock used by the thermal sensor.
+- #thermal-sensor-cells: should be 0 (see thermal.txt)
+
+Example:
+
+thermal-zones {
+ cpu_thermal: cpu-thermal {
+ polling-delay-passive = <0>;
+ polling-delay = <1000>;
+
+ thermal-sensors = <&thermal>;
+
+ trips {
+ cpu-crit {
+ temperature = <80000>;
+ hysteresis = <0>;
+ type = "critical";
