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).
