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()
