This series adds support for 4 channel DSP mode (A or B) to OMAP McBSP and also
to the twl4030 codec driver.
As an example the Beagle board file is modified to be able to use 4 channel

The change in twl4030 is made in a way, that it will not enable the 4 channel
mode when the codec is in OPTION2 mode.
Since some of the bits in the OPTION register are shared and have different
effect in OPTION1 and OPTION2 modes, an extra care is taken to prevent unvanted
modification to the register.

The series is on top of Mark's tree in regard of the twl4030 codec, so it is on
top of the 'ASoC: TWL4030: Add VDL path support' from Joonyoung Shim.
