This patch series adds DT support to the kirkwood audio subsystem.

It cancels the previous patch requests: - ARM: kirkwood: enable S/PDIF - ARM: kirkwood: extend the kirkwood i2s driver for DT usage - ARM: kirkwood: extend the kirkwood pcm/dma driver for DT usage

It also contains the merge of kirkwood-i2c and kirkwood-dma into one module, and, the removal of the kirkwood-pcm-audio device. This involves changes in the openrd and t5325 drivers, as in the common Kirkwood machine initialization. These last changes have not been tested.
