iommu/exynos: Add runtime pm support This patch adds runtime pm implementation, which is based on previous suspend/resume code. SYSMMU controller is now being enabled/disabled mainly from the runtime pm callbacks. System sleep callbacks relies on generic pm_runtime_force_suspend/pm_runtime_force_resume helpers. To ensure internal state consistency, additional lock for runtime pm transitions was introduced.
