[PATCH] cpufreq (2/5): x86 driver updates #2 (acpi, longhaul)

- update the VIA Longhaul driver to use frequency table helpers and
  the advanced cpufreq driver registration interface.
- cleanup of the ACPI P-States cpufreq driver
- very small update of the core -- set 24API values ahead of the setpolicy
  call.
