[ALSA] SoC WM8753 codec support

This patch series adds support for the WM8753 codec as found on the
OpenMoko Neo 1973 (other Neo 1973 and Samsung S3C24xx patches to follow
today) as well other new devices.
Features:-
 o HiFi and Voice DAI supported (inc runtime switching of DAI mode)
 o DAPM
 o All mixers
 o PLL calculator
 o 16,20 and 24bit samples.
 o WM8753 I2C ID added to include/linux/i2c-id.h
