Any TFTP or DHCP boot on the Davinci OMAP-L138 LCDK board requires
that the 'ethaddr' variable be defined. There are no e-fuses to store
the ethernet mac address for this platform, and neither is a MAC
address reserved in any format. So enable random MAC address support
so that networking boot can be supported.

I haven't seen this patch either in master or next branch yet. Just want
to make sure that this has not fallen into some cracks.
