arm64:dts:mc3: Enable hysteresis and reduce drive-strength for AC97

Tobias Kahlki requested to merge enhance_mc3_ac97 into linux-5.15.32-seco

The signals of some AC97 codecs is not stable enough over the whole temperature range. Enable the hysteresis for clock and input data lines. Also reduce the drive-strength of the sync and output data lines to reduce over-/undershoot on them.
