ASoC: dt-binding: Add bindings for Allwinner A64 codec's analog path controls
The internal codec on Allwinner A64 is split into 2 parts. The analog path controls are routed through an embedded custom register bus accessed through the PRCM block just as on A23/A33/H3. Add a binding for this hardware. Signed-off-by: Vasily Khoruzhick <anarsoul@gmail.com> Acked-by: Maxime Ripard <maxime.ripard@bootlin.com> Signed-off-by: Mark Brown <broonie@kernel.org>

+Required properties:
+- compatible: must be one of the following compatibles:

+- reg: must contain the registers location and length
