drm/bridge: synopsys: dw-mipi-dsi: Force input bus flags
The DATAEN_ACTIVE_LOW bit in DSI_DPI_CFG_POL register is set to zero,
so set the DRM_BUS_FLAG_DE_HIGH flag in input_bus_cfg.flags. It appears
that the DRM_BUS_FLAG_PIXDATA_SAMPLE_NEGEDGE flag also makes sense, so
set it in input_bus_cfg.flags too. With this patch, the flags set by
drm_atomic_bridge_propagate_bus_flags() are overridden (see comment in
that function) in case any downstream bridges propagates invalid flags
to this bridge. A real problematic case is to connect a RM67191 MIPI
DSI panel whose driver sets DRM_BUS_FLAG_DE_LOW and
DRM_BUS_FLAG_PIXDATA_SAMPLE_POSEDGE bus flags.
