dt-bindings: dma: renesas,rz-dmac: document RZ/{T2H,N2H}
The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs have three
DMAC instances. Compared to the previously supported RZ/V2H, these SoCs
are missing the error interrupt line and the reset lines, and they use
a different ICU IP.
Document them, and use RZ/T2H as a fallback for RZ/N2H as the DMACs are
entirely compatible.
