Currently driver use phy_start_aneg() in arc_emac_open() to bring up PHY. But phy_start() function is more appropriate for this purposes. Besides that it call phy_start_aneg() as part of PHY startup sequence it also can correctly bring up PHY from error and suspended states. So the patch replace phy_start_aneg() to phy_start().
Also the patch add call to phy_stop() to arc_emac_stop() to allow the PHY device to be fully suspended when the interface is unused.
