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).
