mtd: rawnand: omap2: Pass the parent of pdev to dma_request_chan()
Commit e1e6255c311b ("mtd: rawnand: omap2: convert driver to nand_scan()") moved part of the init code in the ->attach_chip hook and at the same time changed the struct device object passed to dma_request_chan() (&pdev->dev instead of pdev->dev.parent).
