ide: use ide_build_sglist() and ide_destroy_dmatable() in non-PCI host drivers

* Make ide_build_sglist() and ide_destroy_dmatable() available also when
  CONFIG_BLK_DEV_IDEDMA_PCI=n.

* Use ide_build_sglist() and ide_destroy_dmatable() in {ics,au1xxx-}ide.c
  and remove no longer needed {ics,au}ide_build_sglist().

There should be no functionality changes caused by this patch.
