ASoC: kirkwood: enable Kirkwood driver for mvebu platforms

The audio unit found in the Armada 370 SoC is similar to the one used in the Marvell Kirkwood and Marvell Dove SoCs. Therefore, this commit allows the Kirkwood audio driver to be built on mvebu platforms, and adds an additional compatible string to identify the Armada 370 variant of the audio unit.
