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. BRANCH=none BUG=chrome-os-partner:25933 TEST=emerge-nyan_big coreboot chromeos-bootimage See panel correctly initialized and got DEV screen.
