ARM: dts: cm-t335: add audio support 

The TLV320AIC23B codec is connected to the CPU by McASP controller 1 for
data and I2C0 for control.

Modifications:
- Enable and configure McASP controller 1.
- Add TLV320AIC23B codec pinmux.
- Add TLV320AIC23B codec configurations.
- Use simple-audio-card as CPU to codec glue.
