[PATCH i-g-t 4/4] tests/intel/kms_pm_dc: Scope PSR handling to output

[Jeevan B <jeevan.b@intel.com>]

Stop using global PSR checks by passing NULL to PSR helpers.
Select a PSR-capable eDP output and scope PSR enablement and
verification to that output.

This fixes incorrect behavior on multi-eDP systems where PSR
capability differs across panels.
