Driver reports "Synopsys ID: 0x37", so it could be 3.70a or 3.710, as
those are the only compatibles available for 3.7x.

It's worth noting the driver does not rely on the compatibles for
implementing version specific logic, as it gets the IDs directly from
chip registers.

The usage of generic snps,dwmac fallback was borrowed from downstream code.

Cristian
