[COMMON] iommu/exynos: remove rpm-enabled check in suspend/resume

After removing CONFIG_PM_RUNTIME, pm_runtime_enabled() always returns
zero because sysmmu driver calls pm_runtime_enable() at probe time.
It results SFR access in suspend/resume callback even though power block
is off. To avoid SFR access, condition checking by pm_runtime_enabled()
is removed by this patch.
