ide: remove the legacy ide driver
The legay ide driver has been replace with libata starting in 2003 and has been scheduled for removal for a while. Finally kill it off so that we can start cleaning up various bits of cruft it forced on the block layer. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
