[meta-xilinx] Problem with Ethernet Clock Speed [dizzy]

[Nathan Rossi]

Just an update on this, I have updated the machine configs to better
represent the machine's features including the rtc backfill.

http://git.yoctoproject.org/cgit/cgit.cgi/meta-xilinx/commit/?id=e059e4a799df52e68ab01fa42c56733d90fba7af
http://git.yoctoproject.org/cgit/cgit.cgi/meta-xilinx/commit/?id=edca777d4af70095654794ae8ca462d77c93b308

If i have missed something please let me know.

Thanks,
Nathan
