You might want to look at what phy_optional_get() does.  If the phy
does not exist in DT, it does not return an error, but a NULL phy.
You can pass NULL to all the other calls generic phy_ calls. If there
is a real error, it returns it. That makes the driver code much
simpler.

You might want to consider adding clk_optional_get() and
devm_clk_optional_get().
