ASoC: cs4349: Fix suspend/resume

Browse source 
dev_get_drvdata() will not return the snd_soc_runtime to which this CODEC
is attached, so the current code will result in undefined behavior.
To fix this just use regmap_update_bits(cs4349->regmap, ...) directly
instead of snd_soc_update_bits(rtd->codec, ...).
