[U-Boot] [PATCH] tegra2: trivially enable 13 mhz crystal frequency

[Marek Vasut]

Dear Lucas Stach,

> This is needed for upcoming Toradex Colibri T20 upstream support.

Neat, you're doing support for this board? That'd be great to have :) Keep me in 
CC, I have one and I'd be glad to review patches. (I hope you noticed the work 
of antmicro on the tegra/u-boot)
