ASoC: stac9766: Remove ac97_read/ac97_write wrappers
Since the regmap conversion ac97_read/ac97_write are just simple wrappers around snd_soc_read/snd_soc_write. Use those instead directly and remove the wrappers. Also use snd_soc_update_bits() where appropriate. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
