Initialise the V4L2 async notifier after registering the V4L2 device, just
before parsing DT for async sub-devices. This way the device can be made
available to the V4L2 async framework from the notifier init time onwards.
A subsequent patch will add struct v4l2_device as an argument to
v4l2_async_nf_init().
