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.
