Remove legacy CDROM drivers
They are all broken beyond repair. Given that nobody has complained about them (most haven't worked in 2.6 AT ALL), remove them from the tree. A new mitsumi driver that actually works is in progress, it'll get added when completed. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

1/* -- ISP16 cdrom detection and configuration
2 *
3 * Copyright (c) 1995,1996 Eric van der Maarel <H.T.M.v.d.Maarel@marin.nl>
4 *
5 * Version 0.6
6 *
7 * History:
8 * 0.5 First release.
9 * Was included in the sjcd and optcd cdrom drivers.
10 * 0.6 First "stand-alone" version.
11 * Removed sound configuration.
12 * Added "module" support.
13 *
14 * 9 November 1999 -- Make kernel-parameter implementation work with 2.3.x
15 * Removed init_module & cleanup_module in favor of
16 * module_init & module_exit.
17 * Torben Mathiasen <tmm@image.dk>
18 *
19 * 19 June 2004 -- check_region() converted to request_region()
20 * and return statement cleanups.
21 * - Jesper Juhl
22 *
23 * Detect cdrom interface on ISP16 sound card.
24 * Configure cdrom interface.
25 *
26 * Algorithm for the card with OPTi 82C928 taken
27 * from the CDSETUP.SYS driver for MSDOS,
28 * by OPTi Computers, version 2.03.
29 * Algorithm for the card with OPTi 82C929 as communicated
30 * to me by Vadim Model and Leo Spiekman.
