bindings: PCI: layerscape: Add 'dma-coherent' property Add 'dma-coherent' description for PCI nodes. The 'dma-coherent' indicates that the hardware IP block can ensure the coherency of the data transferred from/to the IP block. This can avoid the software cache flush/invalid actions, and improve the performance significantly. The PCI IP block of ls1043a has this capability, so adding this feature to improve the PCI performance.
