An Adaptive-Sync-capable DP protocol converter indicates its support by setting the related bit in the DPCD register. Computes AS SDP values based on the display configuration, ensuring proper handling of Variable Refresh Rate (VRR) in the context of Adaptive Sync. --v2: - Update logging to Patch-1 - use as_sdp instead of async - Put definitions to correct placeholders from where it is defined. - Update member types of as_sdp for uniformity. - Correct use of REG_BIT and REG_GENMASK. - Remove unrelated comments and changes. - Correct code indents. - separate out patch changes for intel_read/write_dp_sdp. --v3: - Add VIDEO_DIP_ASYNC_DATA_SIZE definition and comment in as_sdp_pack function to patch 2 as originally used there. [Patch 2]. - Add VIDEO_DIP_ENABLE_AS_HSW flag to intel_dp_set_infoframes [Patch 3].
