[PATCH v7 2/3] i2c: mux: Set adapter physical device

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

For i2c muxes, the parent of the mux adapter device is the adapter
device the mux is connected to.

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

Fill the adap.physdev with the mux device.
