phylib: Fix auto-negotiation restart avoidance
A previous patch, 51e2a3846eab18711f4eb59cd0a4c33054e2980a, made genphy_config_aneg() not restart aneg by calling genphy_restart_aneg() if the advertisement hadn't changed. But, genphy_restart_aneg() doesn't just restart aneg, it may also *enable* aneg or un-isolate the PHY from the MII (those functions are controlled by the same register). The code to avoid calling genphy_restart_aneg() didn't consider this. So, modify genphy_config_aneg() to also check if the PHY needs to have aneg enabled or be un-isolated before deciding not to restart aneg. This caused a problem with certain Davicom PHYs, as that driver isolates the PHY (why?) before calling genphy_config_aneg() and expects the PHY to be un-isolated by that function.
