This patch adds the following property for arc_emac. 1) phy-reset-gpios: The phy-reset-gpio is an optional property for arc emac device tree boot. Change the binding document to match the driver code. 2) phy-reset-duration: Different boards may require different phy reset duration. Add property phy-reset-duration for device tree probe, so that the boards that need a longer reset duration can specify it in their device tree. Anyway, we can add the above property for arc emac.
