If CONFIG_SPL_OS_BOOT is enabled and Linux image is not flashed at RAW_MODE_KERNEL_SECTOR in MMC, spl still assumes that Linux is available and tries to boot it and hangs. In order to avoid this, adding a check to verify if parsed image header is of type IH_OS_LINUX. If it fails then fall back to load u-boot image.
