hw/arm/exynos4210: Move exynos4210_combiner_get_gpioin() into exynos4210.c

The function exynos4210_combiner_get_gpioin() currently lives in
exynos4210_combiner.c, but it isn't really part of the combiner
device itself -- it is a function that implements the wiring up of
some interrupt sources to multiple combiner inputs.  Move it to live
with the other SoC-level code in exynos4210.c, along with a few
macros previously defined in exynos4210.h which are now used only
in exynos4210.c.
