Set .cmd_size in the SCSI host template instead of using the SCSI pointer
from struct scsi_cmnd. This patch prepares for removal of the SCSI pointer
from struct scsi_cmnd. The ARM SCSI drivers have been identified as follows:
$ git grep -l '#include.*arm_scsi.h'
drivers/scsi/arm/acornscsi.c
drivers/scsi/arm/cumana_2.c
drivers/scsi/arm/eesox.c

The following two header files have the same file name: include/scsi/scsi.h
and drivers/scsi/scsi.h. This is confusing. Remove the latter since the
following note was added in drivers/scsi/scsi.h in 2004:
"NOTE: this file only contains compatibility glue for old drivers. All
these wrappers will be removed sooner or later. For new code please use
the interfaces declared in the headers in include/scsi/"

Commit 756fb6a895 ("scsi: acornscsi: Remove tagged queuing vestiges")
mistakenly introduced a reference to function scsi_cmd_to_tag(). This
function does not exist as it was removed from an earlier series version
when I upstreamed the named commit - originally authored By Hannes - but
this reference still remained.
Fix by replacing the reference to scsi_cmd_to_tag() with
scsi_cmd_to_rq(scsi_scmd)->tag, which scsi_cmd_to_tag() was a wrapper for.

The acornscsi driver has a config option to enable tagged queuing, but this
option gets disabled in the driver itself with the comment 'needs to be
debugged'. As this is a _really_ old driver I doubt anyone will be wanting
to invest time here, so remove the tagged queue vestiges and make our lives
easier.

The same effects can be achieved by setting the dma_boundary to
PAGE_SIZE - 1 and the max_segment_size to PAGE_SIZE, so shift those
settings into the drivers. Note that in many cases the setting might
be bogus, but this keeps the status quo.
[mkp: fix myrs and myrb]

This driver already sets the dma_boundary to PAGE_SIZE - 1, which
has the same result.

Most SCSI drivers want to enable "clustering", that is merging of
segments so that they might span more than a single page. Remove the
ENABLE_CLUSTERING define, and require drivers to explicitly set
DISABLE_CLUSTERING to disable this feature.

While testing with the ARM specific memset() macro removed, I ran into a
compiler warning that shows an old bug:
drivers/scsi/arm/fas216.c: In function 'fas216_rq_sns_done':
drivers/scsi/arm/fas216.c:2014:40: error: argument to 'sizeof' in 'memset' call is the same expression as the destination; did you mean to provide an explicit length? [-Werror=sizeof-pointer-memaccess]
It turns out that the definition of the scsi_cmd structure changed back
in linux-2.6.25, so now we clear only four bytes (sizeof(pointer))
instead of 96 (SCSI_SENSE_BUFFERSIZE). I did not check whether we
actually need to initialize the buffer here, but it's clear that if we
do it, we should use the correct size.
Fixes: de25deb180 ("[SCSI] use dynamically allocated sense buffer")
