You got me :-) [1]
The DATA2 and DATA3 (for QSPI0_B "lane") are used for other purposes -
this is how the PCB was designed.
At best it is possible to have both memories working with double SPI
configuration or single (QSPI0_A with quad SPI [2]).
(And hence it is why I've asked Andrey for sharing his DTS files).
