[ALSA] soc - ASoC 0.13 WM9712 codec driver
This patch updates the WM9712 codec driver to the new API in ASoC 0.13. Changes:- o Removed DAI capabilities matching code in favour of manual matching in the machine drivers. o Added DAI operations for codec and CPU interfaces. o Removed config_sysclk() function and struct snd_soc_clock_info. No longer needed as clocking is now configured manually in the machine drivers. Also removed other clocking data from structures.
