From: Patrice Chotard <patrice.chotard@st.com>
Since dtc v1.4.6-9-gaadd0b65c987, aliases property name must include only lowercase and '-'.
After having updated all STi boards serial aliases from "ttyASN" to "serialN", st-asc driver need to be updated accordingly as tty aliases id is retrieved using of_alias_get_id().
