Add support for a new AMD Ethernet device called "Crater". It has a new
PCI ID, add this to the current list of supported devices in the
amd-xgbe devices. Also, the BAR1 addresses cannot be used to access the
PCS registers on Crater platform, use the indirect addressing via SMN
instead.

Changes since v1:
 - A new cleanup patch is introduced to reorganize the code using helper
   functions.
 - New XGBE_XPCS_ACCESS_V3 type has been introduced handle the Crater
   device XPCS handling.
 - Used FIELD_GET() and FIELD_PREP() helpers
