With the intel_pstate driver and turbo enabled, the top frequency in
the frequency array is the P1+1, i.e. 2300001, whereas the frequency
shown in scaling_cur_freq could be a lot higher.

This patch adds a flag to the check_cur_freq function so that we can
specify if a frequency is greater than expected (turbo mode), in which
case the check should be successful.

Fixes: aeaeaf5f2d62 ("test/power: add cases for turbo feature")

Nitpicking, but stdbool exists :) it would be nice to use bool type for 
bool variables, not int.

Dave, I think you missed this comment.

Thanks for the reminder Thomas, I've just pushed a new version replacing 
the int with a bool.

Regards,
Dave.
