Changes of V3:
* Put TMU node directly into t1040si-post.dtsi file.
* Add fsl,tmu-range property.
* Change calibration property to fsl,tmu-calibration.
* Update the calibration data.
Changes of V2:
* Provide more details on compatible and calibration properties.

+Required properties:
+- compatible : Must include fsl,qoriq-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 : Temperature range for TMU. Including the starting
+ temperature and number of calibration points for each range.
+- fsl,tmu-calibration : Calibration table for TMU. This is required to
+ determine what a specific sensor reading translates to in degrees
+ Celsius. There are four calibration ranges, for each range we need
+ a couple of calibration data formatted like TTCFGR, TSCFGR.
+ Freescale provides the data required.
