Enable DMA transfer to/from SRC in r8a7793/gose device tree.
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 tring
SSI0 -> SRC2
SSI1 <- SRC3
Based on similar work for the r8a7791/koeslch by Kuninori Morimoto.
