tty: Remove baudrate dead code & make ktermios params const
With the architectures currently in-tree, either: 1) CBAUDEX is zero 2) The earlier BOTHER if check covers cbaud < 1 case 3) All CBAUD bits are covered by the baud_table Thus, the check for cbaud being out-of-range for CBAUDEX case cannot ever be true. The ktermios parameters can now be made const.
