Add CAN bus pinmux.
Enable D_CAN bus controllers 0 and 1
The pinmux of uart1 node contradicts the pinmux of dcan0 and dcan1 nodes.
U-Boot should delete the uart1 or dcan0/1 nodes.

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.
