[PATCH v2 03/24] dt-bindings: net: dwmac: Fix the TSO property declaration

[Serge Semin <Sergey.Semin@baikalelectronics.ru>]

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. The original allwinner sunXi bindings file also didn't have the
TSO-related property declared. Taking all of that into account 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.

Signed-off-by: Serge Semin <Sergey.Semin@baikalelectronics.ru>

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.

Changelog v2:
- Use correct syntax of the JSON pointers, so the later would begin
  with a '/' after the '#'.
