    Before commit 0e30f472 ("mtd: spi-nor: add support for DTR protocol"),
    for all PP command, it only support 1-1-1 mode, no matter the tx setting
    in dts. But after the upper commit, the logic change. It will choose
    the best mode(fastest mode) which flash device and spi-nor host controller
    both support.
    
    qspi and fspi host controller do not support read 1-4-4 mode. so need to
    set the tx to 1, let the common code finally select read 1-1-4 mode.
