Convert the Xen ARM device tree binding documentation from the legacy
plain-text format (Documentation/devicetree/bindings/arm/xen.txt) to
the DT schema format, as required by the modern DT binding process.
The "hypervisor" node is named without a unit-address. The name is part
of the Xen ABI and is matched verbatim by the kernel using strcmp() in
arch/arm/xen/enlighten.c and arch/arm64/kernel/acpi.c. Allow a
unit-address so this can be addressed and the dtc warnings can be
avoided in the example.
