Subject: [PATCH 0/6] Zap SCIF2 DMA configuration in R-Car Gen3 DTS

This series is triggered by a regression on M3 targets caused by
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=703db5d1b175
("arm64: dts: renesas: r8a7796: Enable DMA for SCIF2"), when applied
on top of rcar-3.9.x Renesas official kernel.

This collection of patches attempts to consistently propagate the fix
across the existing R-Car3 DTS. Full story is placed into
commit ("Revert "arm64: dts: renesas: r8a7796: Enable DMA for SCIF2"").

While debugging drivers/tty/serial/sh-sci.c, a minor update avoiding
__ptrval__ in dev_dbg() is included here as well.

Tested using v5.1-rc7-131-gea9866793d1e on:
 - H3-ES2.0-ULCB
 - M3N-ES1.1-ULCB
 - M3-ES1.1-Salvator-XS
