Not all platform currently supports octal DTR mode. lx2160a do not
implement DQS, this causes flash probe failure and therefore, provide
an option of quirk FSPI_QUIRK_DISABLE_DTR for platforms not support
DTR mode.

You write "DQS is not supported" but your quirk targets DTR. DTR works
without DQS. DQS is needed for faster frequencies, no? So the quirk
should be named accordingly.

Also, this compatible is (unfortunately!) also used on for the LS1028A
SoC and as far as I know DQS is supported there. I'm not sure what to
do here. Maybe add a new compatible "nxp,ls1028a-fspi" and change the
device tree to
compatible = "nxp,ls1028a-fspi", "nxp,lx2160a";
