This patch add the support of GPF[1-5] pin of Exynos5433 SoC. The GPFx need
to support the multiple memory map because the registers of GPFx are located
in the different domain.

I suppose this patch is adding the compatible string because it was
forgotten in earlier patch? I believe it should be split into separate
patch and mentioned in description.

Note that it makes it incompatible with previous DT bindings, because
the extra resource becomes mandatory now. But if there was no DTS for
any Exynos5433 in the tree before then I guess it's okay.
