tty: cyclades, remove this orphan

The Cyclades driver was orphaned by commit d459883e (MAINTAINERS:
remove two dead e-mail) 13 years ago. Noone stepped up to take care of
them and to fix all the issues the driver has.

On the top of that, there is no way to obtain the firmware for Z cards
from the vendor as cyclades.com ceased to exist.

So it's time to drop the driver with all its traces.

the status of the Cyclades-Z ports every certain amount of time

status of the Cyclades-Z ports. The default op mode is polling. If
