Subject: [PATCH v8 3/6] arm64: dts: ti: k3-am625-sk: Enable audio on AM62
SK
Add nodes for audio codec and sound card, enable the audio serializer
(McASP1) under use from SK-AM62 E2 [1] onwards and update pinmux.
Keep all audio related nodes in the common dtsi as they are exactly the
same between SK-AM62 and SK-AM62-LP.
