While researching some PM behaviour within I2C, I found out that the i2c-demux driver does not play well with that due to broken relationship with other devices. Patch 1 ensures the right parent-child relationship. Patch 2 makes the connection between the demux device and the demuxed bus similar to that we have in the mux core.
Tested on a Renesas Lager board (R-Car H2).
