kms_cursor_legacy tests cursor flips with various scenarios. Scenarios include flip tests with one or more screens, modesettings with blocking and non-blocking cases and atomic and legacy commits.

The failures are happening on TGL platform. The dmesg shows that hang occurred during DP link training as the aux channel communication timeouts. eDP still seems to work. The reasons for incomplete tests could be anything from loose connector/broken hw to sw bug or a hiccup in CI environment. Whatever the reason, from user perspective, it is annoying if the the display doesn't light up.

Seems to continue to happen off and on. Setting high/normal to continue watching.
