ASoC: dt-bindings: sun4i-a10-codec: add hp-det-gpios

Devices integrating Allwinner SoCs may use line-out or headphone jacks
with jack detection circuits attached to a GPIO. Support defining these
in DTs.

A number of Anbernic devices featuring the H700 SoC use this mechanism
to switch between a headphone jack and an internal speaker, so add these
to the allowed routing items.
