The generic barebox-dt-2nd.img depends on the user to fish out
the correct device tree from arch/${SRCARCH}/dts and to instruct
the preceding boot stage to pass that device tree to the barebox image.
To make this easier, especially with an eye towards using this as a
coreboot payload, let's have the barebox build system produce a FIT
image combining barebox-dt-2nd.img and all the enabled device trees.
As this introduces a python3 and python3-libfdt dependency that wasn't
there before, this is only built by default if CONFIG_BOARD_GENERIC_FIT
is enabled or make barebox.fit is explicitly invoked.

ARM: dts: add device trees for the QEMU Virt machine
treewide: collect the name of all board device trees
kbuild: collect available device trees in dtbs-list
scripts: add new scripts_dtc target
kbuild: restrict dtbs target to enabled DTs by default
kbuild: improve make help description
kbuild: allow dependency on any file in images/
arch: maintain Linux kernel and mkimage ARCH mapping in Kconfig
arch: make BOARD_GENERIC_DT a user-selectable option across archs
images: add barebox FIT image target
MAKEALL: rename target in symbols to more appropiate defconfig
MAKEALL: add support for building arbitrary targets
ci: container: add python3-libfdt dependency for barebox.fit
