ide: remove ->dma_master field from ide_hwif_t (take 5)
* Convert cmd64x, hpt366 and pdc202xx_old host drivers to use
pci_resource_start(hwif->pci_dev, 4) instead of hwif->dma_master.
* Remove no longer needed ->dma_master field from ide_hwif_t.
v2:
* Use the more readable 'hwif->dma_base - (hwif->channel * 8)' instead of
pci_resource_start(hwif->pci_dev, 4).
v3:
* Use hwif->extra_base in hpt366/pdc20xx_old + some cosmetic fixups over v2
(suggested by Sergei).
v4:
* Correct offsets in hpt3xxn_set_clock().
v5:
* Use hwif->extra_base in hpt366 for _real_ this time. (Noticed by Sergei)
