Subject: [PATCH v3 1/9] media: i2c: ds90ub9x3: Fix sub-device matching

1029939b3782 ("media: v4l: async: Simplify async sub-device fwnode
matching") recently changed how async sub-device matching works. This
breaks the UB9x3 drivers, as they set the subdev.fwnode to an endpoint.
Afaiu, the fix is simply to not set subdev.fwnode at all.
