dt-bindings: PCI: renesas,pci-rcar-gen2: Add device tree support for R9A06G032
Add internal PCI bridge support for the R9A06G032 SOC. The Renesas RZ/N1D
(R9A06G032) internal PCI bridge is compatible with the one present in the
R-Car Gen2 family, but compared to R-Car Gen2, it needs three clocks
instead of one.
The 'resets' property is not required for the RZ/N1 family.
