It's a bit too narrow text in the commit message, can you use more width?

So, I believe this is expected to be a temporary change and something like
fwnode_get_phy_mode() is on its way, correct?

This can be translated to fwnode_find_reference(), but it might require more
changes.

Actually you may start from converting drivers one-by-one to fwnode
APIs (as much as it's possible), and then do with a library call. Up to you.
