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.
