[PATCH] ARM: nommu: avoid mapping vectors page when !CONFIG_MMU

When running without an MMU, we do not need to install a mapping for the
vectors page. Attempting to do so causes a compile-time error because
install_special_mapping is not defined.

This patch adds compile-time guards to the vector mapping functions
so that we can build nommu configurations once more.

I had a similar patch a few days ago doing the same thing... when Greg's
acked it, please submit to the patch system, thanks.
