The new `intel_dp_compute_as_sdp` function computes AS SDP values based on the display configuration, ensuring proper handling of Variable Refresh Rate (VRR). --v2: - Add DP_SDP_ADAPTIVE_SYNC to infoframe_type_to_idx().[Ankit] - separate patch for intel_read/write_dp_sdp [Ankit]. - _HSW_VIDEO_DIP_ASYNC_DATA_A should be from ADL onward [Ankit] - To fix indentation [Ankit] --v3: - Add VIDEO_DIP_ENABLE_AS_HSW flag to intel_dp_set_infoframes. --v4: - Add HAS_VRR check before write as sdp. --v5: - Add missed HAS_VRR check before read as sdp. --v6: Use Adaptive Sync sink status, which can be used as a check for read/write sdp.
