ide: make ide_dma_timeout() available also for CONFIG_BLK_DEV_IDEDMA_SFF=n

Make ide_dma_timeout() available also for CONFIG_BLK_DEV_IDEDMA_SFF=n
and convert {ics,au1xxx-}ide.c to use it.

While at it:
- dump ATA Status register content on error
- use EXPORT_SYMBOL_GPL() to match the rest of SFF DMA functions
