[PATCH] ASoC: dt-bindings: renesas: adjust to R-Car Gen4

[Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>]

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

R-Car Gen4 is not compatible with Gen3, this patch adjusts
to R-Car Gen4.

Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>
---
The "required" with if - then - else on "rcar_sound,ssi" is
always match to "then" even though it is checking "renesas,rcar_sound-gen4" or not.
Why ?? Is it my fault ??
