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>
