OMAPDSS: clean up the omapdss platform data mess
The omapdss pdata handling is a mess. This is more evident when trying to use device tree for DSS, as we don't have platform data anymore in that case. This patch cleans the pdata handling by: - Remove struct omap_display_platform_data. It was used just as a wrapper for struct omap_dss_board_info. - Pass the platform data only to omapdss device. The drivers for omap dss hwmods do not need the platform data. This should also work better for DT, as we can create omapdss device programmatically in generic omap boot code, and thus we can pass the pdata to it. - Create dss functions for get_ctx_loss_count and dsi_enable/disable_pads that the dss hwmod drivers can call.
