The cx20442 codec driver used here requires the TTY layer to be enabled, or we get a link error:
sound/built-in.o: In function `cx20442_codec_remove': cx20442.c:398: undefined reference to `tty_hangup' sound/built-in.o: In function `ams_delta_remove': ams-delta.c:613: undefined reference to `tty_unregister_ldisc' sound/built-in.o: In function `ams_delta_cx20442_init': ams-delta.c:559: undefined reference to `tty_register_ldisc'
This adds the missing dependency in the E3 configuration, there was already one for the codec.
