Please don't add these U-Boot specific properties into these dts/dtsi
files. The preferred way is to create a new dtsi file with the U-Boot
specific additions. This will get included automatically in the build
process. Please see this file for example:

arch/arm/dts/mt7622-u-boot.dtsi

This will also enable us to stay in sync with the Linux DT files.
