The previous commit erroneously noted that the !IORDY filter was turned
on. No true, that change was split out into this commit.

With Tejun having added adev->ap some time ago we can get rid of the
almost unused port being passed to mode filters. And while we are
doing filters, lets turn on the !IORDY filter as well.

Now that we have ata_do_set_mode() available for drivers to use we don't
actually need ->post_set_mode() as the driver can wrap set_mode nicely
and do stuff before or after (eg PCMCIA needs before), so we can kill off
a method in all the structs
While I was at it I added kernel-doc to the function involved.

This alone isn't sufficient to save the universe from prehistoric disks
and controllers but it is a first important step. Split off a separate
function to provide a mode filter when controller iordy is not available.

This splits set_mode into do_set_mode and the wrapper so that a driver can
call the standard method inside its own. This in theory also obsoletes
->post_set_mode().

This changeset revolves around the fact that all the SiS controllers have
the same enable bits, but differing cable detection methods. Previously
that meant each type had its own error_handler methods. Instead we can
now implement different ->cable_detect methods and share a single
error_handler which does the filtering by enable bits.
In addition we had some auto const arrays that should be static const. I'm
not sure if gcc already treats them intelligently but adding the static
will make sure.

There are two changes here. Firstly we switch to a cable detect method,
secondly the old code forgot to call ata_std_prereset() but somehow

2.6.21-rc has horrible problems with libata and PATA cable types (and
thus speeds). This occurs because Tejun fixed a pile of other bugs and
we now do cable detect enforcement for drive side detection properly.
Unfortunately we don't do the process around cable detection right. Tejun
identified the problem and pointed to the right Annex in the spec, this patch
implements the rest of the needed changes.
We add a ->cable_detect() method called after the identify
sequence which allows a host to do host side detection at this point
should it wish, or to modify the results of the drive side identify.
This separate ->cable_detect method also cleans up a lot of code because
many drivers have their own error_handler methods which really just set
the cable type.
If there is no ->cable_detect method the cable type is left alone so a
driver setting it earlier (eg because it has the SATA flags set or
because it uses the old error_handler approach) will still do the right
thing (or at least the same thing) as before.
This patch simply adds the cable_detect method and helpers it doesn't use
them but other follow up patches will (ie Adrian please don't submit
patches to unexport them ;))

The chips covered by sata_mv have a 32-bit DMA boundary they must not
cross, not a 64K boundary. We are merely limited to a 64K maximum
segment size. Therefore, the DMA scatter/gather table fill code can be
greatly simplified, and we need not cut in half the S/G table size as
reported to the SCSI layer.
Also, the driver forget to turn on 64-bit DMA at the PCI layer. All
other data structures (both hardware and software) have been prepped for
64-bit PCI DMA. It was simply never turned on. <fingers crossed> let's
see if it still works...
