This testcase mainly makes sure that ubifs_repair can make UBIFS image be consistent on different flashes (eg. nand, nor). Because the min_io_size of nor flash is 1, the UBIFS image on nor flash will be different from nand flash after doing powercut, so we need make sure ubifs_repair can handle these two types of flash.
