[ALSA] soc - 0.13 ASoC headers
This patch updates the API's to include the new DAI configuration and
clocking architecture.
Changes:-
o Removed DAI automatic matching and capabilities structure (struct
snd_soc_dai_mode) and macros.
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.
o Updated version to 0.13
o Added shift to SOC_SINGLE_EXT kcontrol macro.
