arm64: dts: rockchip: Add PCIe endpoint mode support
Add a device tree node representing PCIe endpoint mode.
The controller can either be configured to run in Root Complex or Endpoint
mode.
If a user wants to run the controller in endpoint mode, the user has to
disable the pcie3x4 node and enable the pcie3x4_ep node.
