[PATCH 03/25] dt-bindings: net: dwmac: Fix the TSO property declaration

Indeed the STMMAC driver doesn't take the vendor-specific compatible
string into account to parse the "snps,tso" boolean property. It just
makes sure the node is compatible with DW MAC 4.x, 5.x and DW xGMAC
IP-cores. Fix the conditional statement so the TSO-property would be
evaluated for the compatibles having the corresponding IP-core version.

While at it move the whole allOf-block from the tail of the binding file
to the head of it, as it's normally done in the most of the DT schemas.

Note this won't break the bindings description, since the "snps,tso"
property isn't parsed by the Allwinner SunX GMAC glue driver, but only
by the generic platform DT-parser.
