The machine driver module and codec driver module don't have
dependency, it is possible that the machine driver is loaded ahead of
the codec driver, then the register_card() will fail and return
EPROBE_DEFER, in this case the driver should not print error log since
this is not a real failure.

For example, I saw this log from a machine with amd renoir audio:
acp_pdm_mach acp_pdm_mach.0: snd_soc_register_card(acp) failed: -517

After applying this patch, there is no error log to confuse users and
audio works after the codec driver is loaded.
