ASoC: nau8822: Disable internal PLL if freq_out is zero
After finishing the playback or recording, the machine driver might
call snd_soc_dai_set_pll(codec, pll_id, 0, 0, 0) to stop the internal
PLL, but with the codec driver nau8822, it will print error as below:
nau8822 0-001a: Unsupported input clock 0
fsl-asoc-card sound-nau8822: failed to stop FLL: -22
Refer to the function wm8962_set_fll() in the codec driver wm8962, if
the freq_out is zero, turn off the internal PLL and return 0.
