sn65dsi83_host_attach is called from probe, so silence message upon
deferred probe. This can happen, e.g. if the bridge driver is built-in, but
the host is built as module.

This might look a bit weird in the first place, but the real benefit is
usage of device_set_deferred_probe_reason() inside dev_err_probe().
Having /sys/kernel/debug/devices_deferred providing more information
actually helped me tracking down an issue.
