Added D_TTY to the cdevswitch flags for all tty drivers. This is required

for the Lite2 fix for always returning EIO in dead_read().

Cleaned up the cdevswitch initializers for all tty drivers.

Removed explicit calls to ttsetwater() from all (tty) drivers.  ttsetwater()
is now called centrally for opens, not just for parameter changes.
