dtc: optionally add add __symbols__ to build-in devicetree
The devicetree overlay driver requires the __symbols__ node to resolve
phandles to the base devicetree. If Barebox has to apply the overlay to
the live devicetree, the build-in devicetree must be built with the
__symbols__ node.
It is configurable, because adding __symbols__ significantly increases
the size of the devicetree binary. When configuring Barebox, a developer
should be able to enable or disable devicetree overlay support and as
this only affects the build-in devicetree, which is linked to the image
anyway, use a Kconfig item for configuring the __symbols__.
