41ba653f24 Blackfin: decouple unrelated cache settings to get exact behavior
The current cache options don't really represent the hardware features.
They end up setting different aspects of the hardware so that the end
result is to turn on/off the cache.  Unfortunately, when we hit cache
problems with the hardware, it's difficult to test different settings to
root cause the problem.  The current settings also don't cleanly allow for
different caching behaviors with different regions of memory.

So split the configure options such that they properly reflect the settings
that are applied to the hardware.

It should be 'lose', not 'loose'.

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.
