Define the generic R8A7794 part of the sound device node.
This sound device is a complex one and comprises the Audio Clock Generator
(ADG), Sampling Rate Converter Unit (SCU), Serial Sound Interface [Unit]
(SSI[U]), and Audio DMAC-Peripheral-Peripheral.
It is up to the board file to enable the device.
This patch is based on the R8A7791 sound work by Kuninori Morimoto.

Changes in version 2:
- added "ctu.[01]", "mix.[01]", "dvc.[01]" to the "clock-names" prop;
- added CTU/DVC/MIX subnodes;
- removed SRC0/7/8/9 subnodes;
- added missing colon to the subject.
