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.
