Merge branch 'xgene'

Iyappan Subramanian says:

====================
Add 10GbE support to APM X-Gene SoC ethernet driver

Adding 10GbE support to APM X-Gene SoC ethernet driver.

v4: Address comments from v3
* dtb: resolved merge conflict for the net tree

v3: Address comments from v2
* dtb: changed to use all-zeros for the mac address

v2: Address comments from v1
* created preparatory patch to review before adding new functionality
* dtb: updated to use tabs consistently

v1:
* Initial version
====================
