tegra124: Setup clock PLLD by approximating display panel pixel clock.
PLLD, the clock for display, was previously hard-coded to 306MHz. To support
more different panels, we should calcualte PLLD by panel pixel clock
configuration.
Note existing pixel clock configurations for nyan* boards won't work (they used
to rely on hard-coded approximated values) so the device trees are also
modified.
