ASoC: sunxi: sun4i-codec: silence misleading error in probe

In the case when a codec device is probed before codec analog
controls, snd_soc_register_card() returns -EPROBE_DEFER, resulting in
a misleading error message

    sun4i-codec 1c22c00.codec: Failed to register our card

even if the device is probed successfully later. Use dev_err_probe()
to demote the above error to a debug message.
