[PATCH] cpufreq: governors documentation fixes

I corrected a small error and enhanced the govenor.txt file with the
ondemand daemon because the kernel configs link to the documentation but
ondemand wasn't documentated.  Feel free to include the patch in the
attachment.

------------
The CPUfreq govenor "ondemand" sets the CPU depending on the
current usage. To do this the CPU must have the capability to
switch the frequency very fast.
