There is issue with simple sound card, the simple sound
card can't configure the pll of codec.

[  115.352669] wm8960 1-001a: failed to configure clock
[  115.358843] wm8960 1-001a: ASoC: error at snd_soc_dai_hw_params on wm8960-hifi: -22

So Switch to fsl-asoc-card and the fsl-asoc-card can support
asrc module as front-end component.
