ARCH_MULTIPLATFORM is purely a Kconfig construct to allow separation of
platforms which support being built together, and those which don't.
It provides a certain basic level of support when enabled (such as DT,
CCF, etc.)  It remains enabled even if you only want to build for one
platform in the multi-platform group.
