[PATCH i-g-t 1/2] tests/kms_pm_dc: Ensure PSR is enabled

[Jouni Högander]

In certain cases PSR support is informed, but it doesn't get enabled
due to some limitations. This is causing failures which are actually just
expected behaviour. Fix this by checking PSR is really enabled and skip in
case it is not
