[U-Boot] [PATCH v2 1/2] mtd: OMAP: Enable GPMC prefetch mode

Enable GPMC's prefetch feature for NAND access. This speeds up NAND read access a lot by pre-fetching contents in the background and reading them through the FIFO address. The current implementation has two limitations: a) it only works in 8-bit mode b) it only supports read access Both is
