Add support for XGMAC2 in stmmac
This series adds support for 10Gigabit IP in stmmac. The IP is called XGMAC2
and has many similarities with GMAC4. Due to this, its relatively easy to
incorporate this new IP into stmmac driver by adding a new block and
filling the necessary callbacks.
The functionality added by this series is still reduced but its only a
starting point which will later be expanded.
I splitted the patches into funcionality and to ease the review. Only the
patch 8/9 really enables the XGMAC2 block by adding a new compatible string.
Version 4 addresses review comments of Florian Fainelli and Rob Herring.
NOTE: Although the IP supports 10G, for now it was only possible to test it
at 1G speed due to 10G PHY HW shipping problems. Here follows iperf3
results at 1G:
