ASoC: 88pm860x: Use regmap for I/O
As part of a move to remove the duplication of regmap functionality in ASoC convert the 88pm860x driver to use the regmap from the MFD. This means that we no longer cache the registers so performance will be slightly reduced on I/O operations. Signed-off-by: Mark Brown <broonie@linaro.org>
