The only user of fixed_phy gpio functionality was here:
arch/arm/boot/dts/nxp/vf/vf610-zii-dev-rev-b.dts
Support for the switch on this board was migrated to phylink
(DSA - mv88e6xxx) years ago, so the functionality is unused now.
Therefore remove it.
Note: There is a very small risk that there's out-of-tree users
who use link gpio with a switch chip not handled by DSA.
However we care about in-tree device trees only.
