ARM: LPC32xx: Provide DMA filter callbacks via platform data
The SLC and MLC NAND drivers now need their dma_filter callbacks via platform data to make them independent of single DMA engine drivers. (This also helps fixing build errors of the SLC and MLC drivers when building as modules because direct access to AMBA dma filter functions isn't available via export.)
