Linux doesn't appear to need it, and no 64-bit imx boards in Linux
appear to use them.  Some layerscape boards appear to use these flags.
If it's not necessary for Linux, but it is necessary for U-Boot, it
seems like the -u-boot.dtsi file is the right place to put it.
It's consistent with that was done for the imx8mm-evk-u-boot.dtsi and others [1]
