net: phy: DP83822: Add ability to advertise Fiber connection
The DP83822 can be configured to use a Fiber connection. The strap register is read to determine if the device has been configured to use a fiber connection. With the fiber connection the PHY can be configured to detect whether the fiber connection is active by either a high signal or a low signal. Fiber mode is only applicable to the DP83822 so rework the PHY match table so that non-fiber PHYs can still use the same driver but not call or use any of the fiber features.
