ARM: spear: use multiplatform configuration options.
The spear platform is now multiplatform capable in principle, and everything still builds when enabled. This slightly rearranges the Kconfig options for spear to enable both single- and multiplatform support. As a side-effect, even building the single spear kernel can now enable spear3xx and spear6xx simultaneously, although not together with spear13xx, because they are a different archicture version (v7 instead of v5).
