sun4i-codec: add routing for headphones and internal speaker

The sun4i-codec kernel driver covers a large number of Allwinner SoCs.
The H616 codec has a single line-out route, which is used in concert
with a Toshiba mux chip to send audio to either an internal speaker or
headphone jack on a number of Anbernic handheld gaming devices.

Add a UCM configuration to allow enabling/disabling the speaker amp
depending on whether headphones are in use or not.
