This adds the 'data_swap' parameter to the CFI driver, which enables swapping of data bytes when writing/programming words to the flash. Note, that this specifically means that bytes are not swapped when writing command words to the flash chip. Unless you are using the SAP in an LS102x chip to program an attached 16-bit NOR flash, you hopefully do not need this!
