media: v4l2-fwnode: Simplify v4l2_async_nf_parse_fwnode_endpoints()

Browse source 
There are only one user left of __v4l2_async_nf_parse_fwnode_ep()
since [1], v4l2_async_nf_parse_fwnode_endpoints(). The two
functions can be merged.

The merge of the two highlights a dead code block conditioned by the
argument 'has_port' that always is false and can therefor be removed.

1. commit 0ae426ebd0 ("media: v4l2-fwnode: Remove v4l2_async_notifier_parse_fwnode_endpoints_by_port()")

[Sakari Ailus: Aligned some lines to opening parentheses.]
