However this trick no longer works, as DSS core no longer uses omap_dss_device from a board file to create the real device, so use a global pointer to accomplish this instead, like other SPI panel drivers do.

Make these changes: - DPI isn't supported via the LCD1 overlay manager, remove DPI as a supported output. - the TV manager can suppport DPI, but the omapdss driver doesn't support that yet, we require some muxing at the DSS level, and we also need to configure the hdmi pll in the DPI driver so that the TV manager has a pixel clock. We don't support that yet.
