* Broadcom iProc PCIe controller with the platform bus interface

Required properties:
- compatible: Must be "brcm,iproc-pcie"
- reg: base address and length of the PCIe controller I/O register space
- #interrupt-cells: set to <1>
- interrupt-map-mask and interrupt-map, standard PCI properties to define the
  mapping of the PCIe interface to interrupt numbers
- linux,pci-domain: PCI domain ID. Should be unique for each host controller
- bus-range: PCI bus numbers covered
- #address-cells: set to <3>
- #size-cells: set to <2>
- device_type: set to "pci"
- ranges: ranges for the PCI memory and I/O regions

Optional properties:
- phys: phandle of the PCIe PHY device
- phy-names: must be "pcie-phy"

- brcm,pcie-ob: Some iProc SoCs do not have the outbound address mapping done
by the ASIC after power on reset. In this case, SW needs to configure it

If the brcm,pcie-ob property is present, the following properties become
effective:

Required:
- brcm,pcie-ob-axi-offset: The offset from the AXI address to the internal
address used by the iProc PCIe core (not the PCIe address)
- brcm,pcie-ob-window-size: The outbound address mapping window size (in MB)

Optional:
- brcm,pcie-ob-oarr-size: Some iProc SoCs need the OARR size bit to be set to
increase the outbound window size
