Add nodes for audio codec and sound card, enable the audio serializer (McASP1) under use and update pinmux. The codec (TLV320AIC3106) is also supplied with a DVDD 1.8V supply from the PMIC (TPS6593x) on the SK. [1] As the PMIC driver and devicetree node is missing, skip describing DVDD for now and manually set the OCMV voltage.
