This seems good to me. I was worried that introducing the unconditionnal
call to phy_set_mode_ext() could trigger spurious errors should the
generic PHY driver not support the requested interface, but AFAICT
there's only the zynqmp in-tree that use the 'phys' property with macb,
and the associated generic PHY driver (drivers/phy/phy-zynqmp.c) doesn't
implement a .set_mode, so that looks safe.
