[Intel-gfx] [PATCH i-g-t v3] tests/chamelium: Add common suspend and hibernate tests for DP and HDMI
This adds two new tests: common-hpd-after-suspend and
common-hpd-after-hibernate that are aimed at testing HPD change during
suspend/hibernate for both DP and HDMI, at the same time.
The interest in bringing this test up is to reduce the time spent in
testing, with the downside of less precision regarding the test's
outcome. The per-connector tests are still available to get a more
precise idea of which connector causes a failure, when that happens.
VGA is explicitly excluded from this test as there is currently no
way of doing delayed hpd pulses for it.
The generic hpd suspend/resume test code is split in a dedicated
function, that allow testing one or all possible ports.
