    x86/boot: 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".
    
    Add missing const qualifiers in casts.
    
    Macro get_mb2_data returns values that are const-qualified.
    The results are stored in const struct pointers, hence
    there's no need to cast away the const qualifiers.
