    x86/cpufreq: 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 and also to other
    literals used in the same contexts or near violations, when their positive
    nature is immediately clear. The latter changes are done for the sake of
    uniformity.
