[U-Boot] [PATCH v2] net:kirkwood_egiga.c: MAC addresses programming using write_hwaddr

[Prafulla Wadaskar]

This patch depends upon a patch
http://lists.denx.de/pipermail/u-boot/2010-April/069478.html

Added a new function kwgbe_write_hwaddr for programming egiga
controller's hardware address.
This function will be called for each egiga port being used

This is a significant improvement and better solution for Kirkwood based
boards for MAC address issues that we were facing
