[PATCH v9 2/3] i2c: {mux,atr}: Set adapter physical device

[Herve Codina <herve.codina@bootlin.com>]

For i2c muxes and atrs (address translators), the parent of the mux/atr
adapter device is the adapter device the mux/atr is connected to.

This parent is not the physical device related to the mux/atr adapter.
Indeed, the physical device of the mux/atr adapter is the mux/atr device
itself.

Fill the adap.physdev with the mux/atr device.
