The conditions in this code do not align when doing an SPL build with
split config. Use __maybe_unused to avoid needing to be so explicit.
Of course a better solution would be to refactor all of this to avoid

Add MV88E61XX DSA support:
- update dt to provide internal MDIO bus and port handles.
U-Boot requires a more restrictive subset of the dt bindings
required by Linux for the sake of simplifying code
- update defconfig to remove old driver and enable new one
- replace mv88e61xx_hw_reset weak override with board_phy_config support
for register configuration that is outside the scope of the DSA driver
