Another change that needs to be made to this file (probably as a
separate change that Thierry can squash into one of his earlier changes)
is to move the pcie-controller node; it is currently not in the correct
place in the .dtsi file; it's not sorted by reg addresss.

You could drop that change if the driver named the clock "cml" rather
than "cml0", which as I explained in my previous email seems like a good
idea anyway.

Applying the same reasoning, I wonder if for Tegra 20 too, the PCIe
driver shouldn't expect clock names of just "xclk" and "pll" rather than
"pcie_xclk" and "pll_e".
