This only used the NO MATCH BAR. However standard PCI dt-binding already defines "dma-ranges" to describe the address ranges accessible by PCIe controller. Add support in Cadence PCIe host driver to parse dma-ranges and configure the inbound regions for BAR0, BAR1 and NO MATCH BAR. Cadence IP specifies maximum size for BAR0 as 256GB, maximum size for BAR1 as 2 GB, so if the dma-ranges specifies a size larger than the maximum allowed, the driver will split and configure the BARs. Legacy device tree binding compatibility is maintained by retaining support for "cdns,no-bar-match-nbits".
