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.
