arm64: dts: socfpga: agilex5: Add dma-coherent property

Browse Source 
Add the `dma-coherent` property to these device nodes to inform the
kernel and DMA subsystem that the devices support hardware-managed
cache coherence.

Changes:
 - Add `dma-coherent` to `cdns,hp-nfc`
 - Add `dma-coherent` to both `snps,axi-dma-1.01a` instances
   (dmac0, dmac1)

This aligns the Agilex5 device tree with the coherent DMA-capable
devices accordingly.
