Is running the PLL_P at 408MHz something which requires a lot of work?
If not, please do this and fold it into this patchset. It doesn't look
too nice adding things to upstream which have to be changed/removed
immediately after going in.

Considering that Tegra 30 support is still not really in a usable state
after this patchset and the time left until things have to get ready for
the next merge window, I suppose you could do it the right way from the
start.

Lucas
