These patches add machine driver to instantiate I2S based realtek's ALC5631 based 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 based card hence support for ALC5631 based machine driver is being added.
Most of the code has been pulled from insignal's git for Arndale and modified to suit the maintain syntax. Machine driver has been made DT compatible.
Changes done: - Removed ifdef for of_device_id structure as commented by Mark Brown - Supporting both variants of device name:alc5631 and rt5631 as commented by Mark Brown - Added "return -EINVAL" if cpu_of_node or codec_of_node is not found in dtb, as commented by Anil Kumar
