PCI: iproc: Fix NULL pointer dereference for BCMA
With the inbound DMA mapping supported added, the iProc PCIe driver
parses DT property "dma-ranges" through call to
"of_pci_dma_range_parser_init()". In the case of BCMA, this results in a
NULL pointer deference due to a missing of_node.
Fix this by adding a guard in pcie-iproc-platform.c to only enable the
inbound DMA mapping logic when DT property "dma-ranges" is present.
Fixes: dd9d4e7498de3 ("PCI: iproc: Add inbound DMA mapping support")
