[PATCH 2/2] ASoC: rsnd: explain extended Audio DMAC peri peri address

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto...@renesas.com>

If SoC has extended Audio DMAC peri peri address,
DT needs to select it.
Otherwise, it can select normal Audio DMAC peri peri address.
Extended Audio DMAC peri peri address can use BUSIF4-7,
normal address can't.
