    x86/hpet: make variable 'per_cpu__cpu_bc_channel' static
    
    The variable is only ever used inside the file where it's
    defined, therefore it can have static storage. This also
    resolves a violation of MISRA C:2012 Rule 8.4 due to the absence
    of a declaration prior to the definition.
