This converts the WM2200 codec to use GPIO descriptors. This is a pretty straight-forward conversion, and it also switches over the single in-tree user in the S3C Cragganmore module for S3C 6410. This coded does not seem to get selected or be selectable through Kconfig, I had to hack another soundcard Kconfig entry to select it for compile tests.
