tty: serial: samsung_tty: Mark as wakeup_path on no_console_suspend

Devices not in the wakeup path always have their power domains shut down
on suspend, which breaks no_console_suspend. Use the wakeup path feature
to stop this from happening.

This is somewhat an abuse of the concept as named, but the end result is
exactly what we desire.
