[Krzysztof Kozlowski]

Fix building of exynos defconfig with disabled PM_SLEEP:
CONFIG_PM_SLEEP=n
CONFIG_PM_SLEEP_SMP=n
CONFIG_SUSPEND=n

The build error messages:
arch/arm/mach-exynos/built-in.o: In function `exynos_boot_secondary':
arch/arm/mach-exynos/platsmp.c:111: undefined reference to `exynos_cpu_power_state'
arch/arm/mach-exynos/platsmp.c:112: undefined reference to `exynos_cpu_power_up'
arch/arm/mach-exynos/platsmp.c:116: undefined reference to `exynos_cpu_power_state'
make: *** [vmlinux] Error 1
