459fc208ab cpufreq: remove policy->governor setting in drivers initialization
As policy->governor is already set to CPUFREQ_DEFAULT_GOVERNOR in the
(always built-in) cpufreq core, we do not need to set it in the drivers.
This fixes the sparc64 allmodconfig build failure.

Also, remove a totally useles setting of ->policy in cpufreq-pxa3xx.c.
