Subject: [PATCH 09/16] i2c: mux: Set adapter supplier

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

This parent is not the supplier of the mux adapter. Indeed, the supplier
of the mux adapter is the mux device itself.

Fill the adap.supplier with the mux device.
