exynos_pm_add_dev_to_genpd is used if one or more out of a large
number of Kconfig symbols are enabled. However the new
exynos_defconfig selects none of those, so the function becomes
unused. Marking it so lets the compiler automatically discard
it.
Without this patch, building exynos_defconfig results in:
arch/arm/mach-exynos/pm_domains.c:118:123: warning:
'exynos_pm_add_dev_to_genpd' defined but not used [-Wunused-function]
