[patch 6/6] staging: speakup: Migrate acntsa, bns, dectlk and txprt to ttyio

[Okash Khawaja <okash.khawaja@gmail.com>]

This changes the above four 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. This also moves
spk_serial_synth_probe() into serialio.c in order to segregate those functions
which directly use serial comms into serialio.c.
