[PATCH v2 2/2] arm64: dts: rockchip: rk3588-evb1: describe the PCIe3x4 slot supply

[Shawn Lin]

Move the vpcie3v3 supply of the PCIe3x4 controller into a child node
describing the slot, so that the PCI pwrctrl framework manages it.

The child node is modelled as a PCI bridge, which is what dtc expects
for a node below a PCI host bridge, and carries the regulator that
powers the devices in the slot.
