Gwan-gyeong Mun 3c053a96ef 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.
