[U-Boot] [PATCHv2 14/21] net: sunxi: Have sunxi common functions together

[Olliver Schinagl]

The sun[8x]i network drivers have some common functions. Let's introduce
a common file with the reading of the MAC address as a start.

In the future, we can move more sunxi shared/common code into this file.
