Subject[PATCH] i2c: i2c-mux-gpio: Change log level to debug for probe deferrals
Probe deferral is not an error case. It happens only when
the necessary dependencies are not there yet.

The driver core is already printing a message when a driver
requests probe deferral, so this can be traced in the logs
without these error prints.

This patch changes the error messages from these deferral cases
to debug messages.
