This commit modifies the Armada 370 and Armada 370 DB Device Tree descriptions to use the simple-card DT binding to describe the audio complex of the Armada 370 DB instead of a custom audio machine driver. To do so, it: - Adds the sound-dai-cells properties to the CS42L51 node, the audio controller node and the SPDIF in/out nodes. - Completely changes the description of the sound complex to use the "simple-audio-card" DT binding instead of the "marvell,a370db-audio" DT binding. - Fixes the indentation to properly use tabs instead of spaces.
