dt-bindings: PCI: microchip,pcie-host: Fix DMA coherency property
PolarFire SoC may be configured in a way that requires non-coherent DMA
handling. On RISC-V, buses are coherent by default & the dma-noncoherent
property is required to denote buses or devices that are non-coherent.
For some reason, instead of adding dma-noncoherent to the binding
the pointless, NOP, property dma-coherent was. Swap dma-coherent for
dma-noncoherent.
