mtd, omap: fix case NAND_OMAP_GPMC_PREFETCH not defined
The patch c316f577b4b72d1a1aeb559e9b3fad20808f1ffd breaks siemens boards because prefetch mode is not enabled. I assume it breaks other boards as well that don't use prefetch. This patch sets read_buf to nand_read_buf if NAND_OMAP_GPMC_PREFETCH is not defined.
