scsi: dpt_i2o: Remove obsolete driver

The dpt_i2o driver was fixed to stop using virt_to_bus() in 2008, but it
still has a stale reference in an error handling code path that could never
work. I submitted a patch to fix this reference earlier, but Hannes
Reinecke suggested that removing the driver may be just as good here.

The i2o driver layer was removed in 2015 with commit 4a72a7af462d
("staging: remove i2o subsystem"), but the even older dpt_i2o scsi driver
stayed around.

The last non-cleanup patches I could find were from Miquel van Smoorenburg
and Mark Salyzyn back in 2008, they might know if there is any chance of
the hardware still being used anywhere.
