Revert "dts: socfpga: Add DTS entry for adding the stmmac glue layer for stmmac."

This reverts commit 7e0b4cd062.

The binding changes need to be done differently as well, let's
take them through netdev, and merge the dts changes in a new
patch here.

-Altera SOCFPGA SoC DWMAC controller
-
-The device node has following properties.
-
-Required properties:
- - compatible	: Should contain "altr,socfpga-stmmac"
- - altr,sysmgr-syscon : Should be the phandle to the system manager node that
-   encompasses the glue register, and the register offset.
-
-Sub-nodes:
-The dwmac core should be added as subnode to SOCFPGA dwmac glue.
-- dwmac :	The binding details of dwmac can be found in
-  Documentation/devicetree/bindings/net/stmmac.txt
