Include Cadence core DT schema and define the Cadence platform DT schema
for both Host and Endpoint mode. Note: The Cadence core DT schema could
be included for other platforms using Cadence PCIe core.

-* Cadence PCIe endpoint controller
-
-Required properties:
-- compatible: Should contain "cdns,cdns-pcie-ep" to identify the IP used.
-- reg: Should contain the controller register base address and AXI interface
- region base address respectively.
-- reg-names: Must be "reg" and "mem" respectively.
-- cdns,max-outbound-regions: Set to maximum number of outbound regions
-
-Optional properties:
-- max-functions: Maximum number of functions that can be configured (default 1).
-- phys: From PHY bindings: List of Generic PHY phandles. One per lane if more
- than one in the list. If only one PHY listed it must manage all lanes.
-- phy-names: List of names to identify the PHY.

-* Cadence PCIe host controller
-
-This PCIe controller inherits the base properties defined in
-host-generic-pci.txt.
-
-Required properties:
-- compatible: Should contain "cdns,cdns-pcie-host" to identify the IP used.
-- reg: Should contain the controller register base address, PCIe configuration
- window base address, and AXI interface region base address respectively.
-- reg-names: Must be "reg", "cfg" and "mem" respectively.
-- #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
-- #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.
-
-Optional properties:
-- cdns,max-outbound-regions: Set to maximum number of outbound regions
- (default 32)
-- cdns,no-bar-match-nbits: Set into the no BAR match register to configure the
- number of least significant bits kept during inbound (PCIe -> AXI) address
- translations (default 32)
-- vendor-id: The PCI vendor ID (16 bits, default is design dependent)
-- device-id: The PCI device ID (16 bits, default is design dependent)
-- phys: From PHY bindings: List of Generic PHY phandles. One per lane if more
- than one in the list. If only one PHY listed it must manage all lanes.
-- phy-names: List of names to identify the PHY.
