mg_disk: seperate mg_disk.h again
eec9462088a26c046d4db3100796a340a50890b8 fold mg_disk.h into mg_disk.c, but mg_disk platform driver needs private data for operation. This also make mg_disk.c as machine independent. Seperate only needed structure and defines to mg_disk.h Signed-off-by: unsik Kim <donari75@gmail.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
