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.
