    xen/public: fix violations of MISRA C:2012 Rule 7.2
    
    The xen sources contains violations of MISRA C:2012 Rule 7.2 whose
    headline states:
    "A 'u' or 'U' suffix shall be applied to all integer constants
    that are represented in an unsigned type".
    
    Add the 'U' suffix to integers literals with unsigned type.
    
    For the sake of uniformity, the following changes are made:
    - add the 'U' suffix to integer constants before the '?' operator
