arm: dts: ls1028a-rdb: enable PCIe controllers from U-Boot dtsi
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.
