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