Cyclades says driver should work with up to 128 tty's per pci card
even though they only support 64 now. Also matches FreeBSD behavior.
Print located tty's using new tty naming scheme - ttyCZ?? where ?? are
two hex letters.
Make firmware load on macppc - one le32toh() was missing.
- Note that the FreeBSD driver distributed by Cyclades served as
documentation on how the board works.
- Use the wait-until-pending-I/O-completes-before-loading-parameters
command in czttyparam().
- Pass BREAKs up to the tty later properly.
- Garbage-collect some debugging code.
