[SCSI] aci7xxx_old: delete decade+ obsolete driver 

After getting warnings in an allyesconfig build[1] from this
driver, I decided to remind myself just how old it was, and
whether it warranted fixing.  In the Kconfig help text, I found:

  "This driver will eventually be phased out entirely"

Going back to the history archive, I see the line was added[2]
in Feb 2002, when we moved from v2.4.2.1 ---> v2.4.2.2

So, with over a decade of notification, and multiple major releases
since then, I think we can justify removing this.  Currently we have
people wasting time building it during routine testing, and then
wasting more time re-researching the known reported warnings, only to
find that nobody really is willing to integrate the fixes[3] for it.

A quick search didn't seem to indicate any active user base for it.
If someone happens to have a quirky _old_ card that the eleven year
old "new" driver doesn't work with, then it is entirely reasonable
that they stick with a kernel version that predates this removal.

help
WARNING This driver is an older aic7xxx driver and is no longer
under active development. Adaptec, Inc. is writing a new driver to
take the place of this one, and it is recommended that whenever
possible, people should use the new Adaptec written driver instead
of this one. This driver will eventually be phased out entirely.
This is support for the various aic7xxx based Adaptec SCSI
controllers. These include the 274x EISA cards; 284x VLB cards;
2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and
motherboard based SCSI controllers from Adaptec. It does not support
the AAA-13x RAID controllers from Adaptec, nor will it likely ever
support them. It does not support the 2920 cards from Adaptec that
use the Future Domain SCSI controller chip. For those cards, you
need the "Future Domain 16xx SCSI support" driver.
In general, if the controller is based on an Adaptec SCSI controller
chip from the aic777x series or the aic78xx series, this driver
should work. The only exception is the 7810 which is specifically
not supported (that's the RAID controller chip on the AAA-13x
cards).
Note that the AHA2920 SCSI host adapter is *not* supported by this
driver; choose "Future Domain 16xx SCSI support" instead if you have
one of those.
Information on the configuration options for this controller can be
found by checking the help file for each of the available
configuration options. You should read
<file:Documentation/scsi/aic7xxx_old.txt> at a minimum before
contacting the maintainer with any questions. The SCSI-HOWTO,
available from <http://www.tldp.org/docs.html#howto>, can also
be of great help.
To compile this driver as a module, choose M here: the
module will be called aic7xxx_old.
