drm/bridge: tfp410: Set input_bus_flags in atomic_check
input_bus_flags are specified in drm_bridge_timings (legacy) as well as drm_bridge_state->input_bus_cfg.flags The flags from the timings will be deprecated. Bridges are supposed to validate and set the bridge state flags from atomic_check. Implement atomic_check hook for the same.
