Although there were still some variations in board DTS files based on meson-gxbb SoC but I think those were minor differences from upstream and shouldn't impact boot on these devices.
So switch to upstream DT via mirroring amlogic/ directory from devicetree-rebasing/src/arm64/amlogic/ directory. And thereby directly building DTB from there including *-u-boot.dtsi files from arch/$(ARCH)/dts/ directory.

Do we need all of the Makefile portions of this? One of the things that works today is that trees listed in ONFIG_DEFAULT_DEVICE_TREE (and a few other variables) will be automatically built. We might just need the new Makefiles to just have: include $(srctree)/scripts/Makefile.dts and then the trees a given config will need will be built.
That sounds fine for Amlogic SoC and many others too with CONFIG_DEFAULT_DEVICE_TREE="" CONFIG_OF_LIST="" options available. However, if in future we have truely generalized U-Boot (like efforts for Qcom platform) then CONFIG_OF_LIST="" may become an overloaded choice.
For now, let me drop the Makefile portions.
