net: phylink: Remove unused phylink_init_eee

phylink_init_eee() is currently unused.

It was last added in 2019 by
commit 86e58135bc4a ("net: phylink: add phylink_init_eee() helper")
but it didn't actually wire a use up.

It had previous been removed in 2017 by
commit 939eae25d9a5 ("phylink: remove phylink_init_eee()").

Remove it again.
