[PATCH v2 2/3] arm64: dts: renesas: r8a779g0: Describe root port on R-Car V4H

[Marek Vasut]

Add node which describes the root port into PCIe controller DT node.
This can be used together with pwrctrl driver to control clock and
power supply to a PCIe slot. For example usage, refer to V4H Sparrow
Hawk board.
