HID: wiimote: init EXT/MP during device detection
We normally get EXT hotplug events or poll for MP hotplugging so we don't need to force extension port initialization during device setup. But for gen20 devices, we disable MP polling because MP is always present. However, this prevents MP initialization during device setup and users need to plug another extension to trigger EXT/MP detection. Therefore, we now trigger EXT/MP detection during device setup automatically. This also avoids slightly delayed extension detection and provides sysfs child-devices prior to the "changed"-uevent during device setup.
