fbdev: sh_mipi_dsi: use platform provided register layout and values 



Different sh-mobile SoCs have variations in their MIPI DSI register layouts,
besides, different LCD panels require different configuration parameters. This
patch switches the driver to use platform-provided MIPI DSI parameters.
