Revert the existing patch that rejects HBR3 for all eDP panels that
do not support TPS4. Add a patch to add a quirk for specific panels that
support HBR3 without TPS4 and are unstable with higher rate.
Reject HBR3 only for these panels.

do not support TPS4. Add a patch to add a kernel parameter to limit
the rate to HBR2 for eDP panels that might be unstable with higher

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)
