[PATCH v2 1/1] dt-bindings: rtc: Convert rtc-fsl-ftm-alarm.txt to yaml format

[Frank Li]

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.

Notes:
    Change from v1 to v2
    - file name change to fsl,ls-ftm-alarm.yaml
    - drop description for reg and interrupt
    - add descript items for fsl,rcpm-wakeup
    - add allof rtc.yaml
    - example use node name 'rtc'
    - example interrupt include gic.h

-Required properties:
-- compatible : Should be "fsl,<chip>-ftm-alarm", the
-	       supported chips include
-	       "fsl,ls1012a-ftm-alarm"
-	       "fsl,ls1021a-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>;
