tty: serial: msm_serial: Don't require DT aliases If there isn't a DT alias then of_alias_get_id() will return -ENODEV. This will cause the msm_serial driver to fail probe, when we want to keep the previous behavior where we generated a dynamic line number at probe time. Restore this behavior by generating a dynamic id if the line number is still negative after checking for an alias or in the non-DT case looking at the .id field of the platform device.
