Set CPU speed to 100% in acpi_throttle attach. This is needed for some
systems that boot with this value at the lowest setting. Change the default boot config back to "leave frequency as BIOS set it". Also, fix buglet where acpi_throttle wouldn't be used if p4tcc was present but disabled by the user. MFC after: 1 week
