ASoC: SSM2602: Convert to direct regmap API usage
Mostly a one to one converion. On one occasion the patch replaces a snd_soc_read-snd_soc_write sequence with regmap_update_bits though as it helps to keep the conversion simple. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
