    xen: arm: implement generic multiboot compatibility strings
    
    This causes Xen to accept the more generic names specified in
    http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/Multiboot 
as of
    2014-06-06.
    
    These names are more generic than those proposed by Andre in
    http://thread.gmane.org/gmane.linux.linaro.announce.boot/326 and those
    used in earlier drafts of the /Multiboot wiki page.
    
    This will allow bootloaders to not special case Xen (or at least to reduce
    the amount which is required).
