ar71xx: allow to use large ethernet frames on AR934x SoCs
The hardware supports large ethernet frames. Override the maximum frame length and packet lenght mask in the platform data to allow to use large MTU on the ethernet interfaces. Limit the feature to AR934x SoCs for now. It should work on some other SoCs as well, but those has not been tested yet.
