mtd: onenand: fix build warning for dma type
The samsung onenand driver passes around a dma address token through a void pointer, which is incorrect and leads to warnings like this one: onenand/samsung.c:548:2: warning: passing argument 1 of '__fswab32' makes integer from pointer without a cast [enabled by default] writel(src, base + S5PC110_DMA_SRC_ADDR); ^ This patch makes it use dma_addr_t here, which is more appropriate.
