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.
