[Chin Liang See]

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
