Add Retronix R-Car V4H Sparrow Hawk board based on Renesas R-Car V4H ES3.0
(R8A779G3) SoC. This is a single-board computer with single gigabit ethernet,
DSI-to-eDP bridge, DSI and two CSI2 interfaces, audio codec, two CANFD ports,
micro SD card slot, USB PD supply, USB 3.0 ports, M.2 Key-M slot for NVMe SSD,
debug UART and JTAG.

The board uses split clock for PCIe controller and device, which requires
slight extension of rcar-gen4-pci-host.yaml DT schema, to cover this kind
of description. The DWC PCIe controller driver already supports this mode
of clock operation, hence no driver change is needed.
