U-Boot is located in doc/DocBook instead of Documentation/DocBook as is in
case of the Linux kernel.

tegra20: add clock_set_pllout function

Common practice on Tegra 2 boards is to use the pllp_out4 FO
to generate the ULPI reference clock. For this to work we have
to override the default hardware generated output divider.

This function adds a clean way to do so.
