HID: nintendo: Patch NYXI Hyperion 3 descriptor

Browse Source 
The HID report descriptor for the third-party NYXI Hyperion 3's right
Joy-Con erroneously reports it as using the report ID for the left Joy-Con.
Since it does actually send the report ID for the right Joy-Con, the HID
subsystem rejects it as unknown. Here we patch it to properly report as the
right Joy-Con report ID to ensure the HID subsystem passes it through
properly.
