arm64: dts: renesas: r9a09g047: Add RZ/G3E Sound support

Browse source

Add the snd_rzg3e node for the RZ/G3E SoC with all sub-components:
  - SSI (Serial Sound Interface) units 0-9,
  - SSIU (Serial Sound Interface Unit) units 0-27,
  - SRC (Sample Rate Converter) units 0-9,
  - CTU (Channel Transfer Unit) units 0-7,
  - DVC (Digital Volume Control) units 0-1,
  - MIX (Mixer) units 0-1.

Sub-node names follow the new RZ/G3E sound binding: unprefixed 'ssi',
'ssiu', 'src', 'dvc', 'mix', 'ctu' wrapper nodes instead of the legacy
'rcar_sound,xxx' R-Car prefix.

Wire up all 5 DMA controllers (dmac0-dmac4) for each audio sub-node with
repeated channel names, so that the DMA core can pick the first
available controller.
