ASoC: sunxi: sun50i-codec-analog: Add support for cpvdd regulator supply
On the Allwinner A64 SoCs, the audio codec has a built-in headphone amplifier. This amplifier has a power supply separate from the rest of the analog audio circuitry, labeled cpvdd. This patch adds a DAPM widget for this supply, and ties it to the headphone amp widget.
