Convert Renesas PCIe Host controller bindings documentation to
json-schema. Note that some compatible doesn't contain on
the original documentation so that incremental patches are required
for it.

-
-- reg: base address and length of the PCIe controller registers.
-- #address-cells: set to <3>
-- #size-cells: set to <2>
-- bus-range: PCI bus numbers covered
-- device_type: set to "pci"
-- ranges: ranges for the PCI memory and I/O regions.
-- dma-ranges: ranges for the inbound memory regions.
-- interrupts: two interrupt sources for MSI interrupts, followed by interrupt
- source for hardware related interrupts (e.g. link speed change).
-- #interrupt-cells: set to <1>
-- interrupt-map-mask and interrupt-map: standard PCI properties
- to define the mapping of the PCIe interface to interrupt numbers.
-- clocks: from common clock binding: clock specifiers for the PCIe controller
- and PCIe bus clocks.
-- clock-names: from common clock binding: should be "pcie" and "pcie_bus".
-
-Optional properties:
-- phys: from common PHY binding: PHY phandle and specifier (only make sense
- for R-Car gen3 SoCs where the PCIe PHYs have their own register blocks).
-- phy-names: from common PHY binding: should be "pcie".
-
-Example:
-
-SoC-specific DT Entry:
-
