amd-xgbe: Add a hardware quirk for register definitions

Browse Source 
A newer version of the hardware is using the same PCI ids for the network
device but has altered register definitions for determining the window
settings for the indirect PCS access.  Add support to check for this
hardware and if found use the new register values.
