extcon: arizona: Update DT binding documentation for jack detection
Add additional bindings for both inverting the polarity of the jack detection pins and allowing the use of a second jack detection pin. Note that the second jack detection pin is hard wired in the chip so can only be enabled through the binding, rather than a pin being specified.
