* Temperature Monitor (TEMPMON) on Freescale i.MX SoCs

Required properties:
-- compatible : "fsl,imx6q-tempmon" for i.MX6Q, "fsl,imx6sx-tempmon" for i.MX6SX.
- i.MX6SX has two more IRQs than i.MX6Q, one is IRQ_LOW and the other is IRQ_PANIC,
+- compatible : "fsl,imx6q-tempmon" for i.MX6Q, "fsl,imx6sx-tempmon" for i.MX6SX,
+ "fsl,imx7-tempmon" for i.MX7S/D.
+ i.MX6SX and i.MX7S/D have two more IRQs than i.MX6Q, one is IRQ_LOW and the other is IRQ_PANIC,
when temperature is below than low threshold, IRQ_LOW will be triggered, when temperature
is higher than panic threshold, system will auto reboot by SRC module.
- fsl,tempmon : phandle pointer to system controller that contains TEMPMON
