soc: samsung: exynos-pmu: Annotate online/offline functions with __must_hold
Annotate functions writing to PMU registers to online and offline CPUs
as __must_hold() the necessary spinlock for code correctness. These are
static functions so possibility of mistakes is low here, but
__must_hold() serves as self-documenting code.
