Moving exynos5420_get_pll_clk function definition up in the code to keep it together with rest of SoC_get_pll_clk functions. This makes code more legible and also removes the need of declaration when called before the position of definition in code. Also, renaming exynos5420_get_pll_clk to exynos542x_get_pll_clk because it is being used for both Exynos 5420 and 5800.
