x86: Fix RevF detection in powernow.c
The PowerNow! driver does not support RevF and earlier parts.
The current code checks for RevF processors in a function that
is not called. Change the code path so that RevF processors
are detected and the driver fails registration.
Also fix cpufreq_add_cpu() to handle unsuccessful registration.
