media: v4l: async: Drop v4l2_async_nf_parse_fwnode_endpoints()
The v4l2_async_nf_parse_fwnode_endpoints() function, part of v4l2-fwnode.c, was a helper meant to register one async sub-dev for each fwnode endpoint of a device. The function is marked as deprecated in the documentation and is actually not used anywhere anymore. Drop it and remove the helper function v4l2_async_nf_fwnode_parse_endpoint() from v4l2-fwnode.c. This change allows to make the helper function __v4l2_async_nf_add_connection() visibility private to v4l2-async.c so that there is no risk drivers can mistakenly use it.
