soc: samsung: exynos-pmu: Fix structure initialization

Commit 78b72897a5c8 ("soc: samsung: exynos-pmu: Enable CPU Idle for
gs101") added system wide suspend/resume callbacks to Exynos PMU driver,
but some items used by these callbacks are initialized only on
GS101-compatible boards. Move that initialization to exynos_pmu_probe()
to avoid potential lockdep warnings like below observed during system
suspend/resume cycle:

INFO: trying to register non-static key.
The code is fine but needs lockdep annotation, or maybe
you didn't initialize this object before use?
turning off the locking correctness validator.
