dt-bindings: input: qcom,pm8921-pwrkey: convert to dt-schema 



Convert input/qcom,pm8xxx-pwrkey.txt to YAML, and take in account that
the PM8921 pwrkey compatible is used as fallback for the PM8018 pwrkey.

Qualcomm PM8xxx PMIC Power Key



PROPERTIES



- compatible:

	Usage: required

	Value type: <string>

	Definition: must be one of:

		    "qcom,pm8058-pwrkey"

		    "qcom,pm8921-pwrkey"



- reg:

	Usage: required

	Value type: <prop-encoded-array>

	Definition: address of power key control register



- interrupts:

	Usage: required

	Value type: <prop-encoded-array>

	Definition: the first interrupt specifies the key release interrupt

		    and the second interrupt specifies the key press interrupt.

		    The format of the specifier is defined by the binding

		    document describing the node's interrupt parent.



- debounce:

	Usage: optional

	Value type: <u32>

	Definition: time in microseconds that key must be pressed or release

		    for state change interrupt to trigger.



- pull-up:

	Usage: optional

	Value type: <empty>

	Definition: presence of this property indicates that the KPDPWR_N pin

		    should be configured for pull up.
