[PATCH 08/25] net: stmmac: Add snps,*-config sub-nodes support

[Serge Semin]

Currently the "snps,axi-config", "snps,mtl-rx-config" and
"snps,mtl-tx-config" DT node properties are marked as deprecated when
being defined as a phandle reference to a node with parameters. The new
way of defining the DW MAC interfaces config is to add an eponymous
sub-nodes to the DW MAC device DT node. Make sure the STMMAC driver
supports it.
