[patch 7/7] staging: speakup: migrate acntsa, bns, dummy, ltlk and txprt to ttyio

[okash.khawaja at gmail.com]

This changes the above five synths to TTY-based comms. They were chosen as a
first pass because their serial comms are straightforward, i.e. they don't use
serial input and don't do internal port knocking.
