At the time of building a device-tree file, all the *u-boot.dtsi files
are looked for, in a particular order, and the first file found is
included. Then, the list of files specified in the
CONFIG_DEVICE_TREE_INCLUDES symbol are included.
Combine these files that are to be included into a variable, and then
include all these files in one go.
