[Chin Liang See]

Enabling MTD default partitions if its not defined in board
configuration file. The layout as below
> u-boot partition for storing SPL image
> env partition for storing U-Boot environment
> UBI partition for storing kernel image and filesystem
> boot partition for backward compatibility / raw binary
> rootfs partition for storing filesystem in case boot partition used
