ARM: EXYNOS: Fix build with ARM_CPU_SUSPEND=n
"ARM: EXYNOS: Add support for firmware-assisted suspend/resume" patch
added to arch/arm/mach-exynos/firmware.c new references to functions
from arch/arm/mach-exynos/sleep.S causing the new CONFIG_PM_SLEEP=n
build breakages. Then "ARM: EXYNOS: Fix build with PM_SLEEP=n and
ARM_EXYNOS_CPUIDLE=y" patch tried to fix the CONFIG_PM_SLEEP=n issues
by always building sleep.S which caused the CONFIG_ARM_CPU_SUSPEND=n
build breakage. Fix it by building arch/arm/mach-exynos/sleep.o only
for CONFIG_EXYNOS_CPU_SUSPEND=y and adding appropriate IS_ENABLED()
checks to arch/arm/mach-exynos/firmware.c.
