dt-bindings: rtc: Convert rtc-fsl-ftm-alarm.txt to yaml format 



Convert dt-binding doc "rtc-fsl-ftm-alarm.txt" to yaml format.

Change example's reg to 32bit address and length.
Remove unrelated rcpm@1e34040 in example.

Freescale FlexTimer Module (FTM) Alarm



Required properties:

- compatible : Should be "fsl,<chip>-ftm-alarm", the

	       supported chips include

	       "fsl,ls1012a-ftm-alarm"

	       "fsl,ls1021a-ftm-alarm"

	       "fsl,ls1028a-ftm-alarm"

	       "fsl,ls1043a-ftm-alarm"

	       "fsl,ls1088a-ftm-alarm"

	       "fsl,ls208xa-ftm-alarm"

	       "fsl,lx2160a-ftm-alarm"

- reg : Specifies base physical address and size of the register sets for the

  FlexTimer Module.

- interrupts : Should be the FlexTimer Module interrupt.

- fsl,rcpm-wakeup property and rcpm node : Please refer

	Documentation/devicetree/bindings/soc/fsl/rcpm.txt



Optional properties:

- big-endian: If the host controller is big-endian mode, specify this property.

  The default endian mode is little-endian.



Example:

rcpm: rcpm@1e34040 {

	compatible = "fsl,ls1088a-rcpm", "fsl,qoriq-rcpm-2.1+";

	reg = <0x0 0x1e34040 0x0 0x18>;

	#fsl,rcpm-wakeup-cells = <6>;

};



ftm_alarm0: timer@2800000 {

	compatible = "fsl,ls1088a-ftm-alarm";

	reg = <0x0 0x2800000 0x0 0x10000>;

	fsl,rcpm-wakeup = <&rcpm 0x0 0x0 0x0 0x0 0x4000 0x0>;
