* Axis ARTPEC-6 PCIe interface

This PCIe host controller is based on the Synopsys DesignWare PCIe IP
and thus inherits all the common properties defined in designware-pcie.txt.

Required properties:
- compatible: "axis,artpec6-pcie", "snps,dw-pcie"
- reg: base addresses and lengths of the PCIe controller (DBI),
	the phy controller, and configuration address space.
- reg-names: Must include the following entries:
	- "dbi"
	- "phy"
	- "config"
- interrupts: A list of interrupt outputs of the controller. Must contain an
  entry for each entry in the interrupt-names property.
- interrupt-names: Must include the following entries:
	- "msi": The interrupt that is asserted when an MSI is received
- axis,syscon-pcie: A phandle pointing to the ARTPEC-6 system controller,
	used to enable and control the Synopsys IP.
