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. Cc: Russell King <rmk@arm.linux.org.uk> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
