    xen: Add licence header to device_tree_defs.h
    
    This header have been created by moving code from other part of the
    project and miss a licence header. The original source code was some
    version of GPL or LGPL but we intend to have the public header to be
    MIT so they can be included easily in other projects.
    
    Part of device_tree_defs.h were moved from libxl_arm.c which is
    LGPL-2.1-only. And part were moved from device_tree.h that is
    GPL-2.0-only.
    
    Part of the original code were added by Julien Grall @ Linaro in
    commits c3ba52a84dd8 and 405c167f0ec9 and 886f34045bf0. The other part
    were added by Ian Campbell @ Citrix, with commit 0c64527e7fc9.
