arm64: dts: imx8: change the spi-nor tx
Before commit 0e30f47232ab5 ("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.
