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 v2:
 - Club patches 2 and 3 to avoid build warnings.
 - Fix the smatch warnings.
 - Fix the build errors on arm64


Raju Rangoju (3):
  amd-xgbe: reorganize the code of XPCS access
  amd-xgbe: add support for Crater ethernet device
  amd-xgbe: use smn functions to avoid race
