ARM: dts: r8a7790: Tidyup Audio-DMAC channel for DVC
Current Audio-DMAC is assigned "rx" as Audio-DMAC0, "tx" as Audio-DMAC1.
Thus, DVC "tx" should be assigned as Audio-DMAC1, instead of Audio-DMAC0.
Because of this, current platform board (using SRC/DVC/SSI)
Playback/Capture both will use same Audio-DMAC0
(but it depends on data path).
First note is that this "rx" and "tx" are from each IP point,
it doesn't mean Playback/Capture.
Second note is that Audio DMAC assigned on DT is only for
Audio-DMAC, Audio-DMAC-peri-peri has no entry.
=> Audio-DMAC
-> Audio-DMAC-peri-peri
-- HW connection
Playback case
[Mem] => [SRC]--[DVC] -> [SSI]--[Codec]
rx ~~~~~~~~~~~~
Capture
[Mem] <= [DVC]--[SRC] <- [SSI]--[Codec]
tx ~~~~~~~~~~~~
