    x86/mach-apic: Move generic_*_probe() declarations into genapic.h
    
    ... as the implementations are in genapic/probe.c
    
    This covers the only functions that both setup.c and boot.c were including
    mach_apic.h for, although setup.c was depending on io_apic.h transitively 
too.
    
    The happens to address two MISRA Rule 8.4 violations, as probe.c couldn't
    previously see the declarations.
    
    No functional change.
