    ACPI: Zero pstate/cstate control values in FADT
    
    If these values are non-zero then the kernel will issue
    an SMI for each core (cstate) and package (pstate).
    
    Since we don't do anything with these SMI callbacks we
    can avoid taking the extra SMIs at boot time by zeroing
    these fields.
