dt-bindings: pincfg-node: Add property 'input-debounce-ns'

The StarFive JHB100 SoC hardware supports debounce time configuration
with nanosecond granularity. The existing 'input-debounce' property
uses microseconds, which is insufficient to accurately represent the
hardware's finer timing steps.

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.
