[PATCH v3 02/21] images: make BOARD_ARM_GENERIC_DT available for other arches

[Ahmad Fatoum]

Other architectures would benefit from the generic DT image too.
Add a new arch-agnostic symbol that arches besides ARM can select.

The new symbol itself should not have a prompt as the help text for
each architecture likely differs (e.g. device tree handoff register).
