    8254: Don't setup 8254 interrupt, if it is not selected as interrupt cputimer
    
    8254 interrupt is setup, mainly to support C-state > C1, however, on some
    systems it could cause system freezing during boot.  Change the default value
    of hw.i8254.intr_disable to 1, so more systems could boot by default.
