For some platforms (e.g. stm32mp1) the official way to build U-boot with a device tree other than the board's default requires passing additional make options such as DEVICE_TREE=xxx or EXT_DTB=xxx. Instead of adding each possible option as a parameter in the .in file, add a generic mechanism to allow passing custom make options to U-boot. A similar approach has been adopted by buildroot.
