Skip DMA initialization completely on revs < 0x20 by setting IDE_HFLAG_NO_DMA
host flag and resetting DMA host masks in alim15x3_init_one() (currently
ide_hwif_setup_dma() will try to obtain DMA base and setup PCI bus-mastering
but init_dma_ali15x3() will fail).

Do PDC202xx specific DMA initialization in init_chipset_pdc202xx()
and remove no longer needed init_dma_pdc202xx().

Nowadays BIOS info is not very useful and only confuses users since:

- IDE always tries to use DMA

- BIOS info may not be accurate with modular IDE/libata

  ide_pci_enable() and remove ide_hwif_request_regions() call

* Fix handling of PCI BAR 4 in ide_pci_enable(), then cleanup
