dt-bindings: mtd: cdns,hp-nfc: Add dma-coherent property

Browse Source 
The Cadence HP NAND Flash Controller on supports DMA transactions through
a coherent interconnect. In previous generations SoC (Stratix10 and Agilex)
the interconnect was non-coherent, hence there is no need for dma-coherent
property to be presence. In Agilex 5, the architecture has changed. It
introduced a coherent interconnect that supports cache-coherent DMA.
