f8420b5828 Add a driver for SMI-based SpeedStep. The hardware supports two frequency
settings and is an older version of the same design used for ICH SpeedStep.
It is only known to be available on PIIX4 chipsets.

Many thanks to Bruno Ducrot for writing the driver and Jon Noack for
testing.

15785fbe81 Add support for _PDC/_OSC by advertising that we support direct access to
the PERF_CTL/STS MSRs via the new acpi_get_features() method.  This should
allow newer systems to use SpeedStep.
