convert the scsi layer to use struct device

Here's a huge patch from Tony and Kay that converts the scsi layer to
use struct device instead of class_device.

It doesn't seem like it could be split up any smaller due to the
interconectedness of the whole mess, if you have any suggestions
otherwise, it would be appreciated.

If you want, I can take this through my tree as it does depend on a
previous IB patch to make that portion of the patch much smaller.

After this, all of the class_device code is now finally gone from the
kernel!

thanks,

greg k-h

Subject: SCSI: convert struct class_device to struct device

It's big, but there doesn't seem to be a way to split it up smaller...
