Documentation: of: Document the bindings used by Juno R1 PCIe host bridge 



ARM's Juno R1 board used PLDA XpressRICH3-AXI IP to implement a PCIe host
bridge. Introduce "plda" as vendor prefix for PLDA and document the DT
bindings for PLDA XpressRICH3-AXI IP as well as ARM's Juno R1.

* ARM Juno R1 PCIe interface



This PCIe host controller is based on PLDA XpressRICH3-AXI IP

and thus inherits all the common properties defined in plda,xpressrich3-axi.txt

as well as the base properties defined in host-generic-pci.txt.



Required properties:

 - compatible: "arm,juno-r1-pcie"

 - dma-coherent: The host controller bridges the AXI transactions into PCIe bus

   in a manner that makes the DMA operations to appear coherent to the CPUs.

* PLDA XpressRICH3-AXI host controller



The PLDA XpressRICH3-AXI host controller can be configured in a manner that

makes it compliant with the SBSA[1] standard published by ARM Ltd. For those

scenarios, the host-generic-pci.txt bindings apply with the following additions

to the compatible property:



Required properties:

 - compatible: should contain "plda,xpressrich3-axi" to identify the IP used.
