arm64: dts: ti: k3-am625-phyboard-lyra-rdk: Add Audio Codec

Browse Source 
The Audio Codec runs over the MCASP (Multichannel Audio Serial Port).

Add pinmux for the Audio Reference Clock and MCASP2.

Add DT nodes for Audio Codec, MCASP2, VCC 1v8 and VCC 3v3 regulators.

Additionally, create a sound node that connects our sound card and the
MCASP2.
