ARM: 8325/1: 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. Any direct references to symbols that will remain in the .data section are replaced with explicit PC-relative references.
