ide: make void and rename ide_dma_lostirq() method
Since ide_dma_lostirq() method's result is discarded, make it return 'void'.
While at it, rename the method to dma_lost_irq(), drop the '__' prefix from the
default method's name, and do some cleanups in this method driver-wise:
- in aec62xx.c, rename the method in accordance with other drivers, and get rid
of unnecessary variables there;
- in pdc202xx_old.c, define/use 'hwif' variable;
- in sgiioc4.c, rearrange the code to call the resetproc() method directly.
