arm64: dts: juno: Describe PCI dma-ranges
The PLDA root complex on Juno relies on an address-based lookup table to
generate AXI attributes for inbound PCI transactions, and as such will
not pass any transaction not matching any programmed address range. The
standard firmware configuration programs 3 entries covering the GICv2m
MSI doorbell and the 2 DRAM regions, so add a "dma-ranges" property to
describe those usable inbound windows.
