The code in module ide-cs does not conform to the current standard if
setting CONFIG_PCMCIA_DEBUG to "y", and loading the module with the
option "pc_debug=N". When that is fixed, then a warning results that
version is defined but not used. This patch fixes both situations.

ide_find_port() now depends on ->chipset being set for occupied ide_hwifs[]
slots so all host drivers have to initialize hwif->chipset properly.
This patch fixes a regression on hosts with > 1 port or with a single port
but no devices attached to it for an affected host drivers.

* Merge ->atapi_{in,out}put_bytes and ->ata_{in,out}put_data methods
into new ->{in,out}put_data methods which take number of bytes to
transfer as an argument and always do padding.
While at it:
* Use 'hwif' or 'drive->hwif' instead of 'HWIF(drive)'.
There should be no functional changes caused by this patch (all users
of ->ata_{in,out}put_data methods were using multiply-of-4 word counts).

* 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).

Since 43cc71eed1, the platform modalias
is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable
ATA and IDE platform drivers, to re-enable auto loading.
NOTE: both ata/pata_platform.c and ide/legacy/ide_platform.c claim
to provide "the" platform_pata driver, and there's no build-time
mutual exclusion mechanism. This means that configs which enable
both drivers will make some trouble when hotplugging...
