Power Management: fix configuration check for sched_domain.py
Add checking for "sched_debug" in kernel cmdline parameter.
Without this option, power policy change via sched_mc/smt_power_savings
will not cause any output from dmesg that is needed for sched_domain.py

The signed-off-by line is missing here. Could you please resend with it.
