drivers: gpio: fix optional operations usage

Browse source 
Only provide implementations for optional operations if needed. This
patch deletes quite a few dummy `pin_interrupt_configure` ops (now
optional), and adjusts ifdeffery on some drivers so that optional ops
are only provided if they implement real functionality.
