  Log:
  Probe CPUs after the PCI hierarchy on i386, amd64, and ia64.  This allows
  the cpufreq drivers to reliably use properties of PCI devices for quirks,
  etc.
  - For the legacy drivers, add CPU devices via an identify routine in the
    CPU driver itself rather than in the legacy driver's attach routine.
  - Add CPU devices after Host-PCI bridges in the acpi bus driver.
  - Change the ichss(4) driver to use pci_find_bsf() to locate the ICH and
    check its device ID rather than having a bogus PCI attachment that only
    checked for the ID in probe and always failed.  As a side effect, you
    can now kldload ichss after boot.
  - Fix the ichss(4) driver to use the correct device_t for the ICH (and not
    for ichss0) when doing PCI config space operations to enable SpeedStep.
