This reverts commit af2ea3df851ffa68ad07ff59d4dabadbf33b45ef.
Both empirically and based on the existing documentation, it looks like
SCIF2 does not support DMA. Let's disable it. Full reasoning is given in
commit ("Revert "arm64: dts: renesas: r8a7796: Enable DMA for SCIF2"").
Fixes: af2ea3df851ffa ("arm64: dts: renesas: r8a77995: add DMA for SCIF2")
