Subject: [PATCH 2/7] dt-bindings: dma: rz-dmac: Restrict properties for RZ/A1H

Make sure we don't allow for the clocks, clock-names, resets,
reset-names. and power-domains properties for the Renesas
RZ/A1H SoC because its DMAC doesn't have clocks, resets,
and power domains.

Fixes: 209efec19c4c ("dt-bindings: dma: rz-dmac: Document RZ/A1H SoC")
