drm/i915/dp: Program VSC Header and DB for Pixel Encoding/Colorimetry Format
Function intel_pixel_encoding_setup_vsc handles vsc header and data block setup for pixel encoding / colorimetry format. Setup VSC header and data block in function intel_pixel_encoding_setup_vsc for pixel encoding / colorimetry format as per dp 1.4a spec, section 2.2.5.7.1, table 2-119: VSC SDP Header Bytes, section 2.2.5.7.5, table 2-120:VSC SDP Payload for DB16 through DB18. v2: Minor style fix. [Maarten] Refer to commit ids instead of patchwork. [Maarten] v6: Rebase v7: Rebase and addressed review comments from Ville. Use a structure initializer instead of memset(). Fix non-standard comment format. Remove a referring to specific commit. Add a setting of dynamic range bit to vsc_sdp.DB17. Add a setting of bpc which is based on pipe_bpp. Remove duplicated checking of connector's ycbcr_420_allowed from intel_pixel_encoding_setup_vsc(). It is already checked from intel_dp_ycbcr420_config(). Remove comments for VSC_SDP_EXTENSION_FOR_COLORIMETRY_SUPPORTED. It is already implemented on intel_dp_get_colorimetry_status(). v8: A missing of setting bpc to VSC setup is the pretty fatal case, it replaces DRM_DEBUG_KMS() to MISSING_CASE(). [Maarten] v9: Use a changed member name of struct dp_sdp. it renamed to db from DB.
