[PATCH 2/3] ARM: exynos: move resume code to .text section

This code calls cpu_resume() using a straight branch (b), so
now that we have moved cpu_resume() back to .text, this should
be moved there as well. Note that all the .data references in
the code are already open coded PC relative references.
