Subject: arm64: dts: rockchip: Fix rk356x PCIe register and range mappings
From: Andrew Powers-Holmes <aholmes@xxxxxxxxx>
commit 568a67e742dfa90b19a23305317164c5c350b71e upstream.
The register and range mappings for the PCIe controller in Rockchip's
RK356x SoCs are incorrect. Replace them with corrected values from the
vendor BSP sources, updated to match current DT schema.
These values are also used in u-boot.
