dt-bindings: phy: ti,phy-j721e-wiz: Add *-10g and *-16g to compatible

Add "ti,j721e-wiz-10g" compatible for Torrent wrapper and change
Sierra wrapper compatible to "ti,j721e-wiz-16g". The Torrent and Sierra
phy wiz-wrappers have some subtle differences, so it is better to have
separate compatible properties for them too.
