Are you sure OMAP2_DSS requires ARCH_OMAP2PLUS? I don't see this, and it at least used to not depend on ARCH_OMAP2PLUS. If it does now, I think the correct fix would be to remove the dependency in OMAP2_DSS. I don't think removing ARCH_MULTIPLATFORM support in omapdrm is the correct solution.

This was an unrelated build break which should be fixed in latest master after 'staging: drm/omap: use omapdss low level API'
