tools: Fix the non-effective option -f --frequency

We use global variable TSC_FREQ defined in config.py in each of the analyzers.
And the value set to TSC_FREQ through option -f/--frequency doesn't take effect.

This patch fix it by adding one parameter to each of the analyzers and pass
the value set by -f/--frequency to it instead of use the global one.
