[PATCH v4 01/21] dt-bindings: pincfg-node: Add property 'input-debounce-ns'

Add the property 'input-debounce-ns' to specify debounce time in
nanoseconds as an alternative to the existing 'input-debounce' which
uses microseconds. Make the new property unavailable when the existing
property 'input-debounce' is selected to prevent conflicting definitions.
