When runtime PM is disabled, the pm_runtime_idle() and _enable() functions will be effectively noops and will not result in enable and idle calls at the hwmod level. In order for drivers to still work when runtime PM is disabled, ensure that all hwmods are left in an enabled state so that even without runtime PM management, they will still work.
