cpufreq: Documentation: fix conservative governor freq_step description

Browse Source 
The conservative governor documentation incorrectly states that setting
freq_step to 0 will use the default 5% frequency step. In reality, since
at least commit 8e677ce83b ("[CPUFREQ] conservative: fixup governor to
function more like ondemand logic"), freq_step=0 has always caused the
governor to skip frequency updates entirely.

Correct the documentation to reflect the actual behavior: freq_step=0
disables frequency changes by the governor entirely.
