[PATCH] dt-bindings: net: snps,dwmac: allow stmmaceth-ocp reset name

[muhammad.nazim.amirul.nazle.asmade@altera.com]

From: Nazim Amirul <muhammad.nazim.amirul.nazle.asmade@altera.com>

Arria10 SoCFPGA DWMAC nodes use reset-names = "stmmaceth",
"stmmaceth-ocp", which matches what dwmac-socfpga looks up for the
OCP reset. The generic snps,dwmac binding only allowed "ahb" as the
second reset name, so Arria10 DTS failed schema validation.

Allow "stmmaceth-ocp" as an alternative second reset name and drop
the related TODO from the Altera SoCFPGA DWMAC binding.
