Staging: Netlogic XLR/XLS GMAC driver

Add support for the Network Accelerator Engine on Netlogic XLR/XLS
MIPS SoCs. The XLR/XLS NAE blocks can be configured as one 10G
interface or four 1G interfaces. This driver supports blocks
with 1G ports.

* Implementing 64bit stat counter in software
* All memory allocation should be changed to DMA allocations
* All the netdev should be linked to single pdev as parent
* Changing comments in to linux standred format
