Change the mode for Sharp lq123p1jx31 panel to something more rockchip-friendly such that we can use the fixed PLLs to generate the pixel clock
This should really switch to a display timing instead of exposing a single mode. The display timing has min, typical, max tuples for all the timings values, which would allow the attached driver to vary the timings inside the allowed bounds if it makes sense.
Trying to hit a specific pixel clock to free up a PLL is exactly one of the use cases envisioned for the display timings stuff.
