If you are doing it this way this variable should be static. I'm not
sure if renaming these testcases to pr-* and psr2-* gives any benefit.
I'll guess it is ok, if you want to do that change.

Not really matter of this patch. I think at some point you need one
more patch to differentiate in psr_wait_entry (psr_active_check) based
on output type eDP vs. DP. See Bspec 68920 "Additional programming
considerations (registers common between eDP and DP)".
