HID: wiimote: Add extension support stub
The wiimote supports several extensions. This adds a separate source file which handles all extensions and can be disabled at compile-time. The driver reacts on "plug"-events on the extension port and starts a worker which initializes or deinitializes the extensions. Currently, the initialization logic is not fully understood and we can only detect and enable all extensions when all extensions are deactivated. Therefore, we need to disable all extensions, then detect and activate them again to react on "plug"-events. However, deactivating extensions will generate a new "plug"-event and we will never leave that loop. Hence, we only support extensions if they are plugged before the wiimote is connected (or before the ext-input device is opened). In the future we may support full extension hotplug support, but reverse-engineering this may take a while.
