[Intel-gfx] [PATCH v7 0/8] YCBCR 4:2:0/4:4:4 output support for LSPCON

This patch series adds YCBCR 4:2:0 output support for LSPCON displays.
In order to indicate the color format of output, to the LSPCON device,
a source has to set and send proper AVI infoframes to LSPCON. So this
patch series:
- introduces concept of CRTC output format.
- adds AVI infoframes support for LSPCON.
- then adds YCBCR 4:2:0 and 4:4:4 output support for LSPCON.

Previous versions of this series and its review can be found here:
https://patchwork.freedesktop.org/series/28536/
https://patchwork.freedesktop.org/series/33794/

- In order to address review comment from V2, I have added 2 new patches
  in this series, hence sent V3, and then V4 and to address additional
  comments.
- V5 of the series adds a new patch (first patch) just to
  introduce CRTC_OUTPUT_FORMAT concept, and later adds patches for 4:2:0
  and 4:4:4 outputs.
- V6 fixes a warning in CI builds, related to state->get_config().
- V7 fixes alignment warnings from checkpatch.
