Add missing include to fix build error:
arch/arm/mach-exynos/cpuidle.c:256:1: warning: data definition has no type or storage class [enabled by default]
arch/arm/mach-exynos/cpuidle.c:256:1: error: type defaults to ‘int’ in declaration of ‘module_init’ [-Werror=implicit-int]
arch/arm/mach-exynos/cpuidle.c:256:1: warning: parameter names (without types) in function declaration [enabled by default]

cc1: some warnings being treated as errors
make[1]: *** [arch/arm/mach-exynos/cpuidle.o] Error 1

Build error happens on gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5)
and was introduced by commit 35baa3369d1c (ARM: EXYNOS: convert cpuidle
driver to be a platform driver).
