ide: add short cables support
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.
