tty: Remove baudrate dead code & make ktermios params const

Browse source

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.
