MLK-10183 ASoC: wm8962: separate ALC Coefficients to four reigsters
Attempt to read volatile register when cache_only is set will return
EBUSY. After playback/record, wm8962_runtime_suspend function will set
cache_only flag, so the volitale register ALC2 can't be read from cache.
Separate ALC Coefficients to four reigsters, the volatile register ALC2
will be read from hardware instead of cache.
