This patch simplifies the code by:
- refactoring function parameters from struct device pointer to direct pointer
to struct sysmmu drvdata
- moving list_head enteries from struct exynos_iommu_owner directly to struct
sysmmu_drvdata

Suspend/resume code assumed that the gadget was always enabled and
