ASoC: Samsung: Add arndale_rt5631 machine driver and binding
Adding machine driver to instantiate I2S based realtek's ALC5631 sound card on Arndale board. There are other variants of Audio Daughter Cards for Arndale Board for which support already exists but there is no support for Realtek's alc5631 codec hence support for ALC5631 based machine driver is being added. This patch also documents the device tree binding for the Arndale board based machine driver.
