tty: cyclades: drop broken alt-speed support
Setting an alt_speed using the ASYNC_SPD flags has been deprecated since v2.1.69, and has been broken since v3.10 and commit 6865ff22 ("TTY: do not warn about setting speed via SPD_*") without anyone noticing. Drop the broken alt-speed handling altogether, and add a ratelimited warning about using TIOCCSERIAL to to change speed as being deprecated. Note that using ASYNC_SPD_CUST is still supported.
