iommu/omap: Adapt to runtime pm
Use runtime PM functionality interfaced with hwmod enable/idle functions, to replace direct clock operations and sysconfig handling. Due to reset sequence, pm_runtime_[get|put]_sync must be used, to avoid possible operations with the module under reset. Because of this and given that the driver uses spin_locks to protect their critical sections, we must use pm_runtime_irq_safe in order for the runtime ops to be happy, otherwise might_sleep_if checks in runtime framework will complain. The remaining pm_runtime out of iommu_enable and iommu_disable corresponds to paths that can be accessed through debugfs, some of them doesn't work if the module is not enabled first, but in future if the mmu is idled withouth freeing, these are needed to debug.
