    xen/link: Introduce a common BUGFRAMES definition
    
    Bugframe linkage is identical in all architectures.  This is not surprising
    given that it is (now) only consumed by common/virtual_region.c
    
    Introduce a common BUGFRAMES define in xen.lds.h ahead of rearranging their
    structure.
    
    No functional change.
