[ Upstream commit 06a574c7ef69bd0bd26ed08e35967acb76622ab3 ]
Current Sound is using simple-audio-card which can't support HDMI. To use HDMI sound, we need to use audio-graph-card. But, one note is that r8a7795 has 2 HDMI ports, but r8a7796 has 1. Because of this mismatch, supporting HDMI on salvator-common is impossible. Thus, this patch exchange sound card to audio-graph-card and keep supporting ak4613 as 1st sound node. r8a7795/r8a7796 salvator-x{s} need to add HDMI sound individually.
