I have no idea what to change in the DT to make it work. I found some hints to
create an alias in the DT but everything i tried didn't help.

The qspi node in arch/arm/dts/imx6ul-14x14-evk.dtsi contains an entry for the
flash but it doesn't show up as child in spi_child_post_bind. Maybe its just
the wrong compatible string but I am clueless.
