ASoC: Add WM8350 AudioPlus codec driver The WM8350 is an integrated audio and power management subsystem which provides a single-chip solution for portable audio and multimedia systems. The integrated audio CODEC provides all the necessary functions for high-quality stereo recording and playback. Programmable on-chip amplifiers allow for the direct connection of headphones and microphones with a minimum of external components. A programmable low-noise bias voltage is available to feed one or more electret microphones. Additional audio features include programmable high-pass filter in the ADC input path. This driver was originally written by Liam Girdwood with further updates from me. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

ASoC: Include WM8350 register definitions in CODEC header It's expected behaviour for the CODEC header to provide them but the WM8350 doesn't due to having all the registers together under drivers/mfd. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
