[PATCH 2/2] ASoC: Codec: wm8962: declare ALC Coefficients as 4 separate registers

[Jiada Wang]

As ALC2 register is volatile, declare it as one of ALC Coefficients
register together with other non-volatile registers will cause issue,
in case wm8962 has enter suspend mode, and cache_only flag is set,
any attempt to read from ALC2 will fail.

Instead of declaring one ALC Coefficients register which contains
ALC1 ~ ALC3 and Noise Gate, this patch declares 4 separate registers,
so that regmap can handle these registers differently based on their
classification.
