arm64: dts: hisilicon: hi3798cv200: Add missing dma-ranges
Reboot starts failing on Poplar since commit 8424ecdde7df ("arm64: mm:
Set ZONE_DMA size based on devicetree's dma-ranges"), which effectively
changes zone_dma_bits from 30 to 32 for arm64 platforms that do not
properly define dma-ranges in device tree. It's unclear how Poplar reboot
gets broken by this change exactly, but a dma-ranges limiting zone_dma to
the first 1 GB fixes the regression.
