scsi: ncr53c8xx: Drop CONFIG_ prefix from Zalon-specific compiler defines

scsi: ncr53c8xx: Drop CONFIG_ prefix from Zalon-specific compiler defines

kconfiglint reports:

X001: CONFIG_NCR53C8XX_PREFETCH referenced in Makefile but not
defined in any Kconfig
X001: CONFIG_SCSI_NCR53C8XX_NO_WORD_TRANSFERS referenced in Makefile
but not defined in any Kconfig

The ncr53c8xx SCSI driver uses two preprocessor defines that carry the
CONFIG_ prefix but are not defined in any Kconfig file:

-DCONFIG_NCR53C8XX_PREFETCH
-DCONFIG_SCSI_NCR53C8XX_NO_WORD_TRANSFERS

These are hardcoded compiler flags in drivers/scsi/Makefile, passed only
when CONFIG_SCSI_ZALON is enabled:

ncr53c8xx-flags-$(CONFIG_SCSI_ZALON) \
:= -DCONFIG_NCR53C8XX_PREFETCH -DSCSI_NCR_BIG_ENDIAN \
-DCONFIG_SCSI_NCR53C8XX_NO_WORD_TRANSFERS

The source files ncr53c8xx.c and ncr53c8xx.h check these defines with
#ifdef to enable script prefetching and disable 16-bit word transfers
respectively — both specific to the PA-RISC Zalon SCSI controller's
big-endian bus requirements.

These defines have been present since the initial git import in commit
1da177e4c3f4 ("Linux-2.6.12-rc2"). They predate the modern Kconfig
convention that CONFIG_ prefixed symbols should always originate from
Kconfig. The third define on the same line, SCSI_NCR_BIG_ENDIAN, already
correctly omits the CONFIG_ prefix.

The CONFIG_ prefix is misleading: these are not user-configurable
options and do not appear in any Kconfig menu. They are unconditionally
enabled for all Zalon builds. Remove the CONFIG_ prefix from both
symbols — renaming them to NCR53C8XX_PREFETCH and
SCSI_NCR53C8XX_NO_WORD_TRANSFERS — to match the convention used by
SCSI_NCR_BIG_ENDIAN on the same line and to avoid confusion with actual
Kconfig-managed symbols.

No functional change.

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.

The gdth driver refers to a SCSI parallel, PCI-only HBA RAID adapter which

itself would require a major overhaul before any modifications can be
attempted, but seeing that it's unlikely to have any users left it should
rather be removed completely.
