Convert the qoriq thermal binding to DT schema format using json-schema

Signed-off-by: Anson Huang <Anson.Huang@nxp.com>

Changes since V1:
	- add 'maxItems' for 'fsl,tmu-range' property;
	- add 'minItems'/'maxItems' and items descriptions for 'fsl,tmu-calibration' property;
	- remove description for common property '#thermal-sensor-cells';
	- refine 'fsl,tmu-calibration' format in example.

-* Thermal Monitoring Unit (TMU) on Freescale QorIQ SoCs
-
-Required properties:
-- compatible : Must include "fsl,qoriq-tmu" or "fsl,imx8mq-tmu". The
-	version of the device is determined by the TMU IP Block Revision
-	Register (IPBRR0) at offset 0x0BF8.
-	Table of correspondences between IPBRR0 values and example  chips:
-		Value           Device
-		----------      -----
-		0x01900102      T1040
-- reg : Address range of TMU registers.
-- interrupts : Contains the interrupt for TMU.
-- fsl,tmu-range : The values to be programmed into TTRnCR, as specified by
-	the SoC reference manual. The first cell is TTR0CR, the second is
-	TTR1CR, etc.
-- fsl,tmu-calibration : A list of cell pairs containing temperature
-	calibration data, as specified by the SoC reference manual.
-	The first cell of each pair is the value to be written to TTCFGR,
-	and the second is the value to be written to TSCFGR.
-- #thermal-sensor-cells : Must be 1. The sensor specifier is the monitoring
-	site ID, and represents the "n" in TRITSRn and TRATSRn.
-
-Optional property:
-- little-endian : If present, the TMU registers are little endian. If absent,
-	the default is big endian.
-- clocks : the clock for clocking the TMU silicon.

-Example:
-
