cfi-mtd: Add cfi-mtd driver.
Add cfi-mtd driver, which exports CFI flash to MTD layer. This allows CFI flash devices to be used from MTD layer. Building of the new driver is controlled by CONFIG_FLASH_CFI_MTD option. Initialization is done by calling cfi_mtd_init() from flash_init(). Signed-off-by: Piotr Ziecik <kosmo@semihalf.com> Signed-off-by: Stefan Roese <sr@denx.de>
