        src/sys/dev/acpi: acpi_cpu.c acpi_cpu.h

Log Message:
Fix PR kern/43765 from Scott Ellis.

Note that the solution is not optimal. If ichlpcib(4) provides SpeedStep
support, possible I/O resource conflicts may occur with acpicpu(4). Ideally,
as noted for instance in Windows design documents, ichlpcib(4) should never
expose SpeedStep when ACPI is being used. The probability for potential race
conditions is however very small, being limited to few P4-era machines and
being dependent on user actions.
