The template ops used in spi_nor_spimem_check_pp() and spi_nor_spimem_check_readop() currently set the data phase to 1 byte long. This is problematic for 8D-8D-8D protocol where odd length data phase is invalid since one cycle transfers 2 bytes and odd number of bytes would mean half a cycle is left over. This could result in a controller rejecting the op as "not supported" even though it actually supports the protocol. Change the data length to 2 bytes in these templates. One might argue that this should only be done for 8D-8D-8D operations but when talking about these templates, there is no functional difference between one and two bytes, even in STR modes.
