Add necessary function definitions to compute AS SDP data. 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: - Added DP_SDP_ADAPTIVE_SYNC to infoframe_type_to_idx(). [Ankit] - Separated patch for intel_read/write_dp_sdp. [Ankit] - _HSW_VIDEO_DIP_ASYNC_DATA_A should be from ADL onward. [Ankit] - Fixed indentation issues. [Ankit] --v3: - Added VIDEO_DIP_ENABLE_AS_HSW flag to intel_dp_set_infoframes. --v4: - Added HAS_VRR check before writing AS SDP. --v5: Added missed HAS_VRR check before reading AS SDP. --v6: - Used Adaptive Sync sink status as a check for read/write SDP. (Ankit) --v7: - Remove as_sdp_enable from crtc_state. - Add a comment mentioning current support of DP_AS_SDP_AVT_FIXED_VTOTAL. - Add state checker for AS_SDP infoframe enable.
