[PATCH 4/13] ide-cris: fix ->speedproc and wrong ->swdma_mask

[Bartlomiej Zolnierkiewicz]

[PATCH] ide-cris: fix ->speedproc and wrong ->swdma_mask

* fix ->speedproc to set the drive speed

* this driver doesn't support SWDMA so use the correct ->swdma_mask

* BUG() if an unsupported mode is passed to ->speedproc
