arm64: dts: ls1043a: Add 'dma-coherent' for ls1043a 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. Signed-off-by: Liu Gang <Gang.Liu@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
