* Add ->cable_detect method to ide_hwif_t.
* Call the new method in ide_init_port() if:
- the host supports UDMA modes > UDMA2 ('hwif->ultra_mask & 78')
- DMA initialization was successful (if hwif->dma_base is not set
ide_init_port() sets hwif->ultra_mask to zero)
- "idex=ata66" is not used ('hwif->cbl != ATA_CBL_PATA40_SHORT')
* Convert PCI host drivers to use ->cable_detect method.
While at it:
* Factor out cable detection to separate functions (if not already done).
* hpt366.c/it8213.c/slc90e66.c:

Majority of host drivers using IDE PCI layer set drive->autotune, the only
exceptions are:
generic.c
ns87415.c
rz1000.c
trm290.c
* no ->set_pio_mode method
it821x.c:
* if memory allocation fails drive->autotune won't be set
(but there also won't be ->set_pio_mode method in such case)
piix.c:
* MPIIX controller (no ->init_hwif method so also no ->set_pio_mode method)
However if there is no ->set_pio_mode method there are no changes in behavior
w.r.t. PIO tuning so always set drive->autotune in ide_pci_setup_ports().

- removal of two debugging printk-s (from cs5530.c and sc1200.c)

Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.
This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.
In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

This patch allows users to override both host and device side cable detection
with "ideX=ata66" kernel parameter. Thanks to this it should be now possible
to use UDMA > 2 modes on systems (laptops mainly) which use short 40-pin cable
instead of 80-pin one.
Next patches add automatic detection of some systems using short cables.
Changes:
* Rename hwif->udma_four to hwif->cbl and make it u8.
* Convert all existing users accordingly (use ATA_CBL_* defines while at it).
* Add ATA_CBL_PATA40_SHORT support to ide-iops.c:eighty_ninty_three().
* Use ATA_CBL_PATA40_SHORT for "ideX=ata66" kernel parameter.

Add CONFIG_IDE_PROC_FS (CONFIG_SCSI_PROC_FS rip-off) config option,
disabling it makes IDE driver ~5 kB smaller (on x86-32).
While at it add CONFIG_PROC_FS=n versions of proc_ide_{create,destroy}()
and remove no longer needed #ifdefs.

* add ide_set_dma() helper and make ide_hwif_t.ide_dma_check return
-1 when DMA needs to be disabled (== need to call ->ide_dma_off_quietly)
0 when DMA needs to be enabled (== need to call ->ide_dma_on)
1 when DMA setting shouldn't be changed
* fix IDE code to use ide_set_dma() instead if using ->ide_dma_check directly
v2:
* updated for scc_pata

AMD756 doesn't support host side cable detection. Do disk side only and
don't advice obsolete options.

The core IDE engine on the CS5536 is the same as the other AMD southbridges,
so unlike the CS5535, we can simply add the appropriate PCI headers to
the existing amd74xx code.

Rob Punkunus recently submitted a patch to enable support for MCP51/MCP55 in
the amd74xx driver. This patch was whitespace-corrupted and didn't apply to
2.6.12 since MCP51 support was merged in the 2.6.12-rc series.
Gentoo would like to support this hardware for our upcoming release media, so
I fixed the patch, and here it is :)
