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

By this patch, "dmas/dma-names" under "rcar_sound,ssi" are dropped from "required:" property, because (A) these are not mandatory if it was PIO transfer mode, (B) Json schema if-then-else doesn't work correctly on there for some reasons. see the Link for detail.
