[PATCH 4/7] cpufreq: Do not track governor name for scaling drivers with internal governors.

[dirk . brandewie]

From: Dirk Brandewie <dirk.brandewie@xxxxxxxxx>

Scaling drivers that implement internal governors do not have governor
structures assocaited with them.  Only track the name of the governor
associated with the CPU if the driver does not implement
cpufreq_driver.setpolicy()
