arm64: dts: rockchip: fix rk3576 pcie unit addresses

The rk3576 pcie nodes currently use the apb register as their unit address
which is the second reg area defined in the binding.

As can be seen by the dtc warnings like

../arch/arm64/boot/dts/rockchip/rk3576.dtsi:1346.24-1398.5: Warning (simple_bus_reg): /soc/pcie@2a200000: simple-bus unit address format error, expected "22000000"
../arch/arm64/boot/dts/rockchip/rk3576.dtsi:1400.24-1452.5: Warning (simple_bus_reg): /soc/pcie@2a210000: simple-bus unit address format error, expected "22400000"

using the first reg area as the unit address seems to be preferred.
This is the dbi area per the binding, so adapt the unit address accordingly
and move the nodes to their new position.
