e1000e: 82579 do not gate auto config of PHY by hardware during nominal use
For non-managed versions of 82579, set the bit that prevents the hardware from automatically configuring the PHY after resets only when the driver performs a reset, clear the bit after resets. This is so the hardware can configure the PHY automatically when the part is reset in a manner that is not controlled by the driver (e.g. in a virtual environment via PCI FLR) otherwise the PHY will be mis-configured causing issues such as failing to link at 1000Mbps. For managed versions of 82579, keep the previous behavior since the manageability firmware will handle the PHY configuration.
