  Revert "i2c: designware: Fix reset call order in dw_i2c_plat_probe()" (2024-01-14 09:02:34 +0100)

----------------------------------------------------------------
This cycle, I2C removes the currently unused CLASS_DDC support
(controllers set the flag, but there is no client to use it). Also,
CLASS_SPD support gets simplified to prepare removal in the future.
Class based instantiation is not recommended these days anyhow.
Furthermore, I2C core now creates a debugfs directory per I2C adapter.
Current bus driver users were converted to use it. Then, there are also
quite some driver updates. Standing out are patches for the wmt-driver
which is refactored to support more variants. And a big series for the
designware-driver needed to be reverted because issues have been
reported late in the cycle and no incremental fix has been found yet.
