[PATCH v4 4/7] drm/bridge: mhdp8546: Set input_bus_flags from atomic_check

[Nikhil Devshatwar]

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.
