The commit 642b80d256e ("net: designware: drop compatible altr, socfpga-stmmac") breaks designware ethernet for all ARC boards. It removes "altr, socfpga-stmmac" compatible from "drivers/net/designware.c" without changing compatible in the boards which use it.

Fix that by adding "snps,arc-dwmac-3.70a" compatible string to "drivers/net/designware.c" and using it in ARC boards device tree.
