arm64: dts: ti: Enable audio on SK-AM62(-LP)

Browse Source 
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 [2].
