[PATCH 23/37] ARM: dts: iwg20d-q7-common: Sound DMA support via SRC on DTS

From: Biju Das <biju.das at bp.renesas.com>

DMA transfer to/from SRC

     DMA      DMApp
[MEM] -> [SRC] -> [SSIU] -> [SSI]

     DMA      DMApp
[MEM] <- [SRC] <- [SSIU] <- [SSI]

Current sound driver is supporting SSI/SRC random connection.
So, this patch is trying
SSI1 -> SRC3
SSI0 <- SRC2
