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.

Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

---
Changes in version 3:
- added back (now disabled) SRC0 node;
- refreshed the patch.

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.

In renesas-devel-20160509-v4.6-rc7, that should be

        power-domains = <&sysc R8A7794_PD_ALWAYS_ON>;

Gr{oetje,eeting}s,
