Adds the actual mptsas driver, based upon the LSI driver with new work
for SAS transport class integration from Eric Moore and me.

This obviously depends on the SAS transport class.

 - various bits for SAS support from the LSI driver.
 - use the device private data for the fusion target private data.
   this should be using the midlayer target data framework, but we
   can't move over to that until fusion has been switched to the
   generic DV code
 - use target ID and channel from the fusion target private data,
   because those in scsi_device will be different for mptsas

Remove new configuration API from i2o_config

The API-patch is still available from the I2O website (which is mentioned in
the kernel config now).  It is removed because it creates a new binary
sysfs-attribute, which doesn't have the limitiation of 4k.  Expect for the
Adaptec controllers, which has a limitation in the hardware this attribute
doesn't make sense anywhere else.  Until the sysfs API provides an attribute
which doesn't buffer (like firmware) and let access to at least 64k blocks i
provide a separate patch...

(akpm: basically, this API was introduced post-2.6.12 and Markus wants to pull
it out before 2.6.13).

Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

scsi_add_host is the proper place to set the device, but people copy
the scsi_set_device usage from older drivers again and again.

note that this leaves some legacy drivers like qlogicisp/qlogicfc
without pci association in sysfs, but they're scheduled to go away soon
anyway.

This patch updates all the device attribute callbacks that weren't
updated with the new parameter, I guess because they weren't in Greg's
tree (including drivers/pcmcia/ds.c). Without the patch these
callbacks are probably broken (and generate a warning along the lines
of "assignment from incompatible pointer type").

Please see http://lkml.org/lkml/2005/5/19/40 for the scripts I used to
update the attributes automatically.
