thermal: devfreq_cooling: Fix perf state when calculate dfc res_util
The issue occurs when the devfreq cooling device uses the EM power model
and the get_real_power() callback is provided by the driver.
The EM power table is sorted ascending，can't index the table by cooling
device state，so convert cooling state to performance state by
dfc->max_state - dfc->capped_state.
