ARM: EXYNOS: Fix build breakage cpuidle on !SMP
The Exynos cpuidle driver has coupled cpuidle built-in so it cannot be built without SMP: arch/arm/mach-exynos/pm.c: In function 'exynos_cpu0_enter_aftr': arch/arm/mach-exynos/pm.c:246:4: error: implicit declaration of function 'arch_send_wakeup_ipi_mask' [-Werror=implicit-function-declaration] arch/arm/mach-exynos/built-in.o: In function 'exynos_pre_enter_aftr': ../arch/arm/mach-exynos/pm.c:300: undefined reference to 'cpu_boot_reg_base' arch/arm/mach-exynos/built-in.o: In function 'exynos_cpu1_powerdown': ../arch/arm/mach-exynos/pm.c:282: undefined reference to 'exynos_cpu_power_down' Fix it by adding missing checks for SMP.
