Previously, there was an omap panel-dpi driver that would read generic timings from the device tree and set the display timing accordingly. This driver was removed so the screen no longer functions. This patch modifies the panel-simple file to setup the timings to the same values previously used.
Fixes: 8bf4b1621178 ("drm/omap: Remove panel-dpi driver")
