This corrects the Ethernet tx/rx clocks in the generated DTB.
Avoids a Linux kernel warning.

Cheers,
Edgar

Correct the GEMs tx/rx clocks to use the 125Mhz fixed-clock.
This matches the setup with the fixed-link 100Mbit PHY.
I also avoids the following warnings from the Linux kernel
driver:

eth0: unable to generate target frequency: 125000000 Hz

Argh, this should say It, not I.

I'll send a v2 keeping the RB tags.
