dt-bindings: thermal: Convert i.MX8MM to json-schema

* Thermal Monitoring Unit (TMU) on Freescale i.MX8MM SoC

Required properties:

- compatible : Must be "fsl,imx8mm-tmu" or "fsl,imx8mp-tmu".

- reg : Address range of TMU registers.

- clocks : TMU's clock source.

- #thermal-sensor-cells : Should be 0 or 1. See ./thermal.txt for a description.

Example:

tmu: tmu@30260000 {

	compatible = "fsl,imx8mm-tmu";

	reg = <0x30260000 0x10000>;

	clocks = <&clk IMX8MM_CLK_TMU_ROOT>;

	#thermal-sensor-cells = <0>;

  i.MX8MM has TMU IP to allow temperature measurement, there are

  currently two distinct major versions of the IP that is supported

  by a single driver. The IP versions are named v1 and v2, v1 is

  for i.MX8MM which has ONLY 1 sensor, v2 is for i.MX8MP which has

  2 sensors.
