Fixed the review issues for pm_rc6_residency IGT case

Browse Source 
Why need add rc6_residency_counter subtest case:
RC6 feature support residency counter,from power consumption aspect,
the counter closer to 1,the better.If the counter is < 0.9, the residency
is not good and will impact power consumption value, if the counter is  > 1,
sysfs file is inaccurate.
