cpufreq: drop K8's driver from beeing selected
Ralf posted a picture of a backtrace from
| powernowk8_target_fn() -> transition_frequency_fidvid() and then at the
| end:
| 932 policy = cpufreq_cpu_get(smp_processor_id());
| 933 cpufreq_cpu_put(policy);
crashing the system on -RT. I assumed that policy was a NULL pointer but
was rulled out. Since Ralf can't do any more investigations on this and
I have no machine with this, I simply switch it off.
