fwnode_graph_parse_endpoint() fwnode argument is now const, therefore make
media_entity_get_fwnode_pad() fwnode argument const as well.

"now", since 2017 :-) I'd phrase the commit message as

The media_entity_get_fwnode_pad() function never modifies its fwnode
argument. Make it const to allow usage of the function in contexts where
the fwnode pointer is const.
