media: v4l2-async: Document asd allocation requirements
The v4l2_async_notifier_add_subdev() function requires the asd pointer
it receives to be allocated dynamically, but doesn't explicitly say so.
Only one driver out of 13 get its right (atmel-sama5d2-isc.c, but with
memory leaks in the error paths), clearly showing we have an issue.
Update the v4l2_async_notifier_add_subdev() documentation to clearly
state the allocation requirement. Whether this will be enough to avoid
new offending code isn't certain, but it's a good first step
nonetheless.
