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

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
