The  idle residency subtests are sensitive to unrelated DRM clients
on the same card. When other processes keep the device busy,
the measured idle residency can be lower than expected and trigger
false failures.

This series improves the robustness of the subtest by first introducing
a helper to enumerate DRM client processes associated with a given card
fd, and subsequently using it in idle residency tests to detect competing
DRM clients triggering a warning, and skipping the test.
