Longhaul - Revert ACPI C3 on Longhaul ver. 2 



Support for Longhaul ver.  2 broke driver for VIA C3 Eden 600MHz with
Samuel 2 core.  Processor is not able to switch frequency anymore.  I
don't know much about this issue at the moment, but until (if ever) I
will know why, this part should be reversed.
