    xen/delay: address MISRA C:2012 Rule 5.3
    
    The variable 'msec' declared in the macro shadows the local
    variable in 'ehci_dbgp_bios_handoff', but to prevent any
    future clashes with other functions the macro is converted to
    a static inline function.
    
    No functional change.
