This is an implementation detail that does not have to be exposed. It was used in WII_IPC whenever the IPC gets reset, but that does not make much sense to me: the only time when IOS loses state and the IPC registers are set up again is when it's reloaded. And reloading IOS already calls Reset() indirectly. Also, an IPC reset from the PPC definitely should not close all opened devices! This also gets rid of a special case for clear_devices, which is now completely unneeded.
