Enabling MTD default partitions if its not defined in board
configuration file. The layout as below
device nor0 <ff705000.spi0>, # parts = 6
#: name size offset mask_flags
0: u-boot 0x00100000 0x00000000 0
1: env1 0x00040000 0x00100000 0
2: env2 0x00040000 0x00140000 0
3: UBI 0x03e80000 0x00180000 0
4: boot 0x00e80000 0x00180000 0
5: rootfs 0x01000000 0x01000000 0
