e1000e: ESB2 config after link up
On ESB2, the MAC-to-PHY (Kumeran) interface must be configured after link is up before any traffic is sent; a new PHY operations function pointer is provided for this. To facilitate read/write of the Kumeran registers without blocking PHY register writes, the driver/firmware synchronization method which previously used a hardware semaphore for both PHY and Kumeran register accesses is now split. New Kumeran register read/write functions utilize this new synchronization method.
