[CPUFREQ] Fix structure name usage in powernow-k8

With 2.6.10-mm2 (or even with -mm1) some structures in struct psb_s have been
renamed in powernow-k8.h, but the renaming has not been done properly for all
occurences in powernow-k8.c.
This prevents cpufreq from accepting the BIOS PST-tables.

The following patch corrects this by renaming the incorrectly named variable
in powernow-k8.c, following the definition in the powernow-k8.h header file.
