[PATCH net-next v3 2/3] dt-bindings: net: allwinner: add H616 EMAC1

[James Hilliard]

The H616 secondary EMAC uses a separate system-control clock register
and supports only RMII at 10/100 Mbps. Add its distinct compatible
without an older fallback, since using the primary EMAC clock register
would not work.

Constrain the PHY interface mode to RMII, matching the hardware.
