ide: add ->mwdma_mask and ->swdma_mask to ide_pci_device_t (take 2)

* Add ->mwdma_mask and ->swdma_mask to ide_pci_device_t.

* Set ide_hwif_t DMA masks using DMA masks from ide_pci_device_t in
  setup-pci.c::ide_pci_setup_ports() (iff DMA base is valid and ->init_hwif
  method may still override them).

* Convert IDE PCI host drivers to use ide_pci_device_t DMA masks.

While at it:

* Use ATA_{UDMA,MWDMA,SWDMA}* defines.

* hpt34x.c: add separate ide_pci_device_t instances for HPT343 and HPT345.

* serverworks.c: fix DMA masks being set before checking DMA base.

v2:
* Add missing masks to DECLARE_GENERIC_PCI_DEV() macro.
