[PATCH] powernow-k8 frequency handling fix

From: Pavel Machek <pavel@ucw.cz>

In 2.6.3, cleanups arrived, and they got test for invalid frequencies
wrong.

Only first frequency is allowed to be < FID_TABLE_BOTTOM, but due to
bug it cleanups it allowed no frequencies < FID_TABLE_BOTTOM. This
fixes it.
