Source components in the display pipeline need to configure their output signals polarities and clock driving edge based on the requirements of the sink component. Those requirements are currently shared across the whole pipeline in the flags of a videomode structure, instead of being local to each bus. This both prevents multiple buses from having different configurations (when the hardware supports it), and makes it difficult to move from videomode to drm_display_mode as the latter doesn't contain bus polarities and clock edge flags. Add a bus_flags field to the omap_dss_device structure and move the DISPLAY_FLAGS_DE_(LOW|HIGH), DISPLAY_FLAGS_PIXDATA_(POS|NEG)EDGE and DISPLAY_FLAGS_SYNC_(POS|NEG)EDGE videomode flags to bus_flags in all external encoders, connectors and panels. The videomode flags are still used internally for internal encoders, this will be addressed in a second step. The related videomode flags in the default mode of the DVI connector can simply be dropped, as they are always overridden by the TFP410 driver. Note that this results in both the DISPLAY_FLAGS_SYNC_POSEDGE and DISPLAY_FLAGS_SYNC_NEGEDGE flags being set, which is invalid, but only the former is tested for when programming the DISPC, so the DVI connector flags are effectively overridden by the TFP410 flags.
