[PATCH v3 1/6] dt-bindings: PCI: dwc: rockchip: Add mandatory atu reg

From: Niklas Cassel <niklas.cassel@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 reg defined, in order to be
able to use this reg, while still making sure 'make CHECK_DTBS=y'
pass, we need to add this reg to rockchip-dw-pcie.yaml.

All compatible strings (rockchip,rk3568-pcie and rockchip,rk3588-pcie)
should have this reg.

The regs in the example are updated to actually match pcie3x2 on rk3568.
