dts: arm:st: stm32h7: fix dma phandle lists

Correct STM32H7xx SoCs DMA lists that were not split by phandle and
seemed to form unique phandles. This is not currently as issue with
existing DT parsing macros and tools but may generate build errors
if tools are more strict on the DTS implementation formats.
