[PATCH 11/13] ARM: spear: use multiplatform configuration options.

[Arnd Bergmann]

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).
