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.

My reading of the documentation is that src0, 7, 8 and 9 are not
present on the r8a7794. I am referring to Figure 38.1b or r1.02 of
the R-Car Gen2 User's Manual.

Indeed, thank you for the timely comment (I'm working on the series respin)! However, table 7A.12 still lists the SRC0/7/8/9 clocks for R8A7794, table 11.1 still lists SRC0/7/8/9 interrupts for R8A7794, and table 43.4 still lists SRC0/7/8/9 MID+RID for R8A7794 -- go figure...
