pinctrl: pinconf-generic: Add property 'input-debounce-ns'
Add 'input-debounce-ns' to the generic parameters used for parsing DT
files, along with the corresponding configuration parameter
PIN_CONFIG_INPUT_DEBOUNCE_NS. This allows debounce time to be specified
in nanoseconds as an alternative to the existing 'input-debounce'
property which uses microseconds
