[PATCH 4/8] ASoC: cs42l56: Constify struct regmap_config and snd_soc_codec_driver

[Krzysztof Kozlowski]

The regmap_config struct may be const because it is not modified by the
driver and regmap_init() accepts pointer to const. Make struct
snd_soc_codec_driver const as well (snd_soc_register_codec() accepts
pointer to const).
