ASoC: codec: arizona: Convert to use GPIO descriptors
This converts the Arizona driver to use GPIO descriptors
exclusively, deletes the legacy code path an updates the
in-tree user of legacy GPIO.
The GPIO lines for mic detect polarity and headphone ID
detection are made exclusively descriptor-oriented. The
headphone ID detection could actually only be used by
the legacy GPIO code, but I converted it to use a
descriptor if someone would actually need it so we don't
just drop useful code.
The compatible "wlf,hpdet-id-gpio" is not in the device
tree bindings and only intended to be used by software
nodes if any. If someone insists I can try to add a
binding for it, but I doubt there is any real user so
it seems pointless.
