[RESEND PATCH v3 29/32] media: davinci: Init async notifier after registering V4L2 device

[Sakari Ailus <sakari.ailus@linux.intel.com>]

Initialise the V4L2 async notifier after registering the V4L2 device, just
before parsing DT for async sub-devices. This way struct device is
available to the notifier right from the beginning which makes it possible
to use it for debug prints.
