Makefile: Add environment variable DEVICE_TREE to header
Users have option to overwrite default device tree (CONFIG_DEFAULT_DEVICE_TREE) via environment variable DEVICE_TREE. Feature has been added long time ago by commit 74de8c9a1672 ("dts/Makefile: Build the user specified dts") for a little bit different reason. But this variable can be also used for different purpose like choosing proper configuration from FIT image in SPL. And this is the functionality I would like to use on Xilinx Zynq devices that current u-boot.img can be composed in the same way based on OF_LIST and different configuration is taken based on platform specific SPL. SPL requires low level ps7_init_gpl configuration that's why different boards require different SPL with fixed board_fit_config_name_match().
