[PATCH v3 3/3] tty: st-asc: Update tty alias

From: patrice.chotard

From: Patrice Chotard <patrice.chotard@xxxxxx>

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().
