[CPUFREQ] powernow-k6: set transition latency value so ondemand governor can be used
Set the transition latency to value smaller than CPUFREQ_ETERNAL so
governors other than "performance" work (like the "ondemand" one).
The value is found in "AMD PowerNow! Technology Platform Design Guide for
Embedded Processors" dated December 2000 (AMD doc #24267A). There is the
answer to one of FAQs on page 40 which states that suggested complete transition
period is 200 us.
Tested on K6-2+ CPU with K6-3 core (model 13, stepping 4).
