Revert the existing patch that rejects HBR3 for all eDP panels that
do not support TPS4. With the patch reverted, the gitlab issue#5969 [1]
will get opened again. Add a quirk to limit the rate to HBR2 for the
device mentioned in [1] and close the issue.

This series is a continuation from [2], and [3].

Rev2:
Instead of revert and add quirk, add a single patch that fixes the
commit. (Jani).

Rev3:
Instead of refining, just revert the patch for now and add quirk for the
ICL machine as a separate patch. (Ville)
