Add a doc to describe the Xen ARM device tree bindings
Changes in v4:
- "xen,xen" should be last as it is less specific;
- update reg property using 2 address-cells and 2 size-cells.

+* Xen hypervisor device tree bindings
+
+Xen ARM virtual platforms shall have the following properties:
+
+- compatible:
+ compatible = "xen,xen-<version>", "xen,xen";
+ where <version> is the version of the Xen ABI of the platform.
+
+- reg: specifies the base physical address and size of a region in
+ memory where the grant table should be mapped to, using an
+ HYPERVISOR_memory_op hypercall.
+
+- interrupts: the interrupt used by Xen to inject event notifications.
+
+
+Example:
+
+hypervisor {
+ compatible = "xen,xen-4.3", "xen,xen";
+ reg = <0 0xb0000000 0 0x20000>;
+ interrupts = <1 15 0xf08>;
+};
