[PATCH 2/8] pci-rcar-gen2: add initial device tree documentation

[Ben Dooks <ben.dooks@codethink.co.uk>]

Add initial documentation for the pci-rcar-gen2 driver device tree bindings.
This is not yet complete and needs work on the sub-nodes for the PCI bus.

+Renesas internal AHB to PCI bridge
+
+This is the bridge used internally to connect the USB controllers to the
+AHB.
+
+Required properties:
+ - compatible: "renesas,pci-r8a7790" for the R8A7790 SoC
+ - reg : A list of physical regions to access the device. The first is
+         the operational registers for the OHCI/EHCI controller and the
+	 second region is for the bridge configuration and control registers.
+ - interrupts : interrupt for the device
+ - clocks : The reference to the device clock
