    xen/ppc: address violations of MISRA C:2012 Rule 11.8
    
    The xen sources contain violations of MISRA C:2012 Rule 11.8 whose
    headline states:
    "A conversion shall not remove any const, volatile or _Atomic qualification
    from the type pointed to by a pointer".
    
    Fix violation by adding missing const qualifier in cast.
