dt-bindings: input: qcom,pm8921-keypad: convert to YAML format
Convert the bindings for the keypad subdevices of Qualcomm PM8921 and PM8058 PMICs from text to YAML format. While doing the conversion also drop the linux,keypad-no-autorepeat The property was never used by DT files. Both input and DT binding maintainers consider that bindings should switch to assertive (linux,autorepeat) instead of negating (no-autorepeat) property.
