ALSA: wss_lib: fix AZT2320 probe.
After the transition from cs4321_lib to wss_lib, azt2320 probe visits snd_ad1848_probe during detection. It expects register 0 (LEFT_INPUT) to be able to retain the value 0xaa during detection but AZT2320 does not support MIC gain meaning it reads back as 0x8a instead.
