[PATCH V2 3/4] dt-bindings: mfd: Convert pm8xxx bindings to yaml

[satya priya <skakit@codeaurora.org>]

Convert pm8xxx bindings from .txt to .yaml format. Also,
split this binding into two: parent binding(qcom-pm8xxx.yaml)
and child node RTC binding(qcom-pm8xxx-rtc.yaml).

Signed-off-by: satya priya <skakit@codeaurora.org>

Changes in V2:
 - As per Bjorn's comments, I've split this into two, one parent binding
   and one child node rtc binding.
 - Fixed bot errors and changed maintainer name.

-= PROPERTIES
-
-- compatible:
-	Usage: required
-	Value type: <string>
-	Definition: must be one of:
-		    "qcom,pm8058"
-		    "qcom,pm8821"
-		    "qcom,pm8921"
-
-- #address-cells:
-	Usage: required
-	Value type: <u32>
-	Definition: must be 1
-
-- #size-cells:
-	Usage: required
-	Value type: <u32>
-	Definition: must be 0
-
-- interrupts:
-	Usage: required
-	Value type: <prop-encoded-array>
-	Definition: specifies the interrupt that indicates a subdevice
-		    has generated an interrupt (summary interrupt). The
-		    format of the specifier is defined by the binding document
-		    describing the node's interrupt parent.
-
-- #interrupt-cells:
-	Usage: required
-	Value type : <u32>
-	Definition: must be 2. Specifies the number of cells needed to encode
-		    an interrupt source. The 1st cell contains the interrupt
-		    number. The 2nd cell is the trigger type and level flags
-		    encoded as follows:
-
-			1 = low-to-high edge triggered
-			2 = high-to-low edge triggered
-			4 = active high level-sensitive
-			8 = active low level-sensitive
-
-- interrupt-controller:
-	Usage: required
-	Value type: <empty>
-	Definition: identifies this node as an interrupt controller
-
-= SUBCOMPONENTS
-
-The PMIC contains multiple independent functions, each described in a subnode.
-The below bindings specify the set of valid subnodes.
-
-== Real-Time Clock
-
-- compatible:
-	Usage: required
-	Value type: <string>
-	Definition: must be one of:
-		    "qcom,pm8058-rtc"
-		    "qcom,pm8921-rtc"
-		    "qcom,pm8941-rtc"
-		    "qcom,pm8018-rtc"
-		    "qcom,pmk8350-rtc"
-
-- reg:
-	Usage: required
-	Value type: <prop-encoded-array>
-	Definition: single entry specifying the base address of the RTC registers
-
-- interrupts:
-	Usage: required
-	Value type: <prop-encoded-array>
-	Definition: single entry specifying the RTC's alarm interrupt
-
-- allow-set-time:
-	Usage: optional
-	Value type: <empty>
-	Definition: indicates that the setting of RTC time is allowed by
-		    the host CPU
