block: cleanup how md_autodetect_dev is called
Add a new include/linux/raid/detect.h header to declare the md_autodetect_dev prototype which can be shared between md and the partition code. Then use IS_BUILTIN to call it instead of the ifdef magic. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
