[PATCH v2 1/4] dt-bindings: PCI: dwc: rockchip: Add atu property

[Niklas Cassel]

From: Niklas Cassel <niklas.cassel at wdc.com>

Even though rockchip-dw-pcie.yaml inherits snps,dw-pcie.yaml
using:

allOf:
  - $ref: /schemas/pci/snps,dw-pcie.yaml#

and snps,dw-pcie.yaml does have the atu property defined, in order to be
able to use this property, while still making sure 'make CHECK_DTBS=y'
pass, we need to add this property to rockchip-dw-pcie.yaml.
