dt-bindings: net: snps,dwmac: add support for Arria10

The hard processor system (HPS) on the Intel/Altera Arria10 provides
three Ethernet Media Access Controller (EMAC) peripherals. Each EMAC
can be used to transmit and receive data at 10/100/1000 Mbps over
ethernet connections in compliance with the IEEE 802.3 specification.
The EMACs on the Arria10 are instances of the Synopsis DesignWare
Universal 10/100/1000 Ethernet MAC, version 3.72a.

Support the Synopsis DesignWare version 3.72a, which is used in Intel's
Arria10 SoC, since it was missing.
