ASoC: sun4i-codec: support hp-det-gpios property

Browse source

[ Upstream commit a149377c03 ]

Add support for GPIO headphone detection with the hp-det-gpios
property. In order for this to properly disable the path upon
removal of headphones, the output must be labelled Headphone which
is a common sink in the driver.

Describe a headphone jack and detection GPIO in the driver, check for
a corresponding device tree node, and enable jack detection in a new
machine init function if described.
