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.

Earlier, the matching of (model,rev) in ide-dma black/white list
handling was to consider "ALL" in the table to match any
revision. This makes NULL to be also an accepted wildcard, and
changes the entries of tables in ide-dma.c to use NULL.
The code still accepts "ALL" as the wildcard, in order to keep
any out-of-tree ide driver that feeds its own table that uses
"ALL" as the wildcard to ide_in_drive_list() function from
breaking.

Fix two minor issues with PCI0646 chip reporting in the init_chipset() method:
"IRQ workaround enabled" message printed out not only for revision 0x01 and
"CMD646: chipset revision" printed twice (by IDE core and the driver itself).
Also, remove empty/pointless switch cases for the chips other than PCI0646,
duplicate write to the MRDMODE register when enabling interrupts and MEMORY
READ LINE cycles, and needless/misplaced initialization of the timing registers
in this method.
Switch to reading only the PCI revision ID register itself, not the whole 32
bits at its address in init_chipset() and init_hwif() methods; in addition,
get rid of the useless clearing of hwif->autodma and perform some cosmetic
style changes in the latter method.
Refactor ata66_cmd64x() by moving all the code into the 'switch' statement,
renaming/adding variables, and fixing the coding style.

Simplify UltraDMA mode filtering in the driver:
- make use of the newly introduced 'udma_mask' field of 'ide_pci_device_t' to
set the correct hwif->ultra_mask, modifying init_setup_hpt366() to select
the correct mask based on the chip revision;
- replace 'max_mode' field of the 'struct hpt_info' with 'max_ultra' specifying
the maximum UltraDMA mode allowed;
- rewrite hpt3xx_udma_filter() to differ the filters based on the 'chip_type'
field, and only use it for HPT366 and HPT370[A] where it's really necessary.

Switch the driver to always program DMA/PIO timings and set device transfer
mode instead of trusting BIOS on CSB6 controllers (libata pata_serverworks.c
driver is also doing things this way and there were no problems reported so
far). While doing conversion I noticed that the old code had many issues:
* the code was assuming that hwif->dma_status is always valid
(which obviously isn't true if hwif->dma_base == NULL)
* value of "(ultra_timing >> (4*unit)) & ~(0xF0)" expression wasn't checked
to fit into udma_modes[5]
* code validating DMA timings didn't validate corresponding PIO timings
* extra CSB5 PIO register wasn't validated et all
* hwif->ide_dma_off_quietly() is always called before ide_set_dma() (which in
turn calls hwif->speedproc() method - svwks_tune_chipset() in this case)
so the code depending on DMA capable bit of DMA status to be set was never
executed (=> the code was never validating DMA timings despite actually
enabling DMA if the PIO timings were OK!)
* on resume driver dependend entirely on BIOS to restore timings and set
transfer mode on the device
While at it:
There is no need to read PIO/MWDMA timings now so don't do it.
