Reuse the scheme implemented by the Kontron SL28 boards in commit d08011d7f9b4 ("arm: dts: ls1028a: disable the PCIe controller by default") and move the 'status = "okay"' lines for the PCIe controllers inside a separate U-Boot dtsi for the LS1028A-RDB board. This way, the existing Linux device tree can simply be dropped in.
