dt-bindings: thermal: convert st,stih407-thermal to DT schema

'st,passive_colling_temp' does not appear in the device-tree, 'reg' and
'#thermal-sensor-cells' are also missing in the device description.

Convert st,stih407-thermal binding to DT schema format in order to clean
unused 'st,passive_cooling_temp' and add missing properties.

-Binding for Thermal Sensor driver for STMicroelectronics STi series of SoCs.
-
-Required parameters:
--------------------
-
-compatible : 	Should be "st,stih407-thermal"
-
-clock-names : 	Should be "thermal".
-		  See: Documentation/devicetree/bindings/resource-names.txt
-clocks : 	Phandle of the clock used by the thermal sensor.
-		  See: Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Optional parameters:
--------------------
-
-reg : 		For non-sysconf based sensors, this should be the physical base
-		address and length of the sensor's registers.
-interrupts :	Standard way to define interrupt number.
-		  NB: For thermal sensor's for which no interrupt has been
-		  defined, a polling delay of 1000ms will be used to read the
-		  temperature from device.
-
-Example:
-
-	temp0@91a0000 {
-		compatible = "st,stih407-thermal";
-		reg = <0x91a0000 0x28>;
-		clock-names = "thermal";
-		clocks = <&CLK_SYSIN>;
-		interrupts = <GIC_SPI 205 IRQ_TYPE_EDGE_RISING>;
-		st,passive_cooling_temp = <110>;
