ide: add ide_dma_prepare() helper
* Add ide_dma_prepare() helper. * Convert ide_issue_pc() and do_rw_taskfile() to use it. * Make ide_build_sglist() static. There should be no functional changes caused by this patch. Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
