Subject: [PATCH 2/2] mtd: lpc32xx_mlc: Adjust to pl08x DMA interface changes

This patch adjusts the LPC32xx MLC NAND driver to the new pl08x DMA interface,
fixing the compile error resulting from changed pl08x structures.

Signed-off-by: Roland Stigge <stigge@...com.de>

Applies to today's linux-next (integrated lpc32xx-next and dma branches which collide)
