ide: add ->cable_detect method to ide_hwif_t
* 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:
- don't check cable type if "idex=ata66" is used
* pdc202xx_new.c:
- add __devinit tag to pdcnew_cable_detect()
* pdc202xx_old.c:
- rename pdc202xx_old_cable_detect() to pdc2026x_old_cable_detect()
- add __devinit tag to pdc2026x_old_cable_detect()
