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.
