I have similar patch in one of my "long forgotten branches", but I'm not 100%
sure whether the cpvdd-supply is required for codec_analog. IIRC, sound worked
for me without the issues on A64-Olinuxino board (Rev D).

'cpvdd-supply = <&reg_eldo1>' for codec_analog

And we also need to enable these configuration options in the defconfig:

+CONFIG_SND_SUN8I_CODEC=m
+CONFIG_SND_SUN50I_CODEC_ANALOG=m
