amd74xx/via82cxxx: use ide_tune_dma()

* Use ide_tune_dma() in amd74xx/via82cxxx driver, this fixes following bugs:
  - DMA capability bit not being checked on the device
  - DMA blacklist not being checked
  - DMA mode being programmed even if drive->autodma == 0
    (thus possibly destroying PIO timings)

* Bump driver version.
