drm/i915/dp: Compute DP tunnel BW during encoder state computation
Compute the BW required through a DP tunnel on links with such tunnels
detected and add the corresponding atomic state during a modeset.
v2:
- Fix error check of intel_dp_tunnel_compute_stream_bw(). (Ville)
- Move intel_dp_tunnel_atomic_cleanup_inherited_state() to this patch.
(Ville)
- Move intel_dp_tunnel_atomic_clear_stream_bw() to this patch.
