falconide/q40ide: add ->atapi_*put_bytes and ->ata_*put_data methods (take 2)
* Add ->atapi_{in,out}put_bytes and ->ata_{in,out}put_data methods to falconide and q40ide host drivers (->ata_* methods are implemented on top of ->atapi_* methods so they also do byte-swapping now). * Cleanup atapi_{in,out}put_bytes(). v2: * Add 'struct request *rq' argument to ->ata_{in,out}put_data methods and don't byte-swap disk fs requests (we shouldn't un-swap fs requests because fs itself is stored byte-swapped on the disk) - this is how things were done before the patch (ideally device mapper should be used instead but it would break existing setups and would have some performance impact).
