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.
