[Intel-gfx] [v9 00/13] Add HDR Metadata Parsing and handling in DRM layer

[Uma Shankar]

This patch series enables HDR support in drm. It basically defines
HDR metadata structures, property to pass content (after blending)
metadata from user space compositors to driver.

Dynamic Range and Mastering infoframe creation and sending.

ToDo:
1. We need to get the color framework in place for all planes
   which support HDR content in hardware. This is already in progres
   and patches are out for review in mailing list.
2. UserSpace/Compositors: Blending policies and metadata blob
   creation and passing to driver. Work is already in progress
   by Intel's middleware teams on wayland and the patches for
   the same are in review.

A POC has already been developed by Ville based on wayland. Please refer
below link to see the component interactions and usage:

v2: Updated Ville's POC changes to the patch series.Incorporated cleanups
and fixes from Ville. Rebase on latest drm-tip.

v3: Fixed a warning causing builds to break on CI. No major change.

v4: Addressed Shashank's review comments.

v5: Rebase on top of Ville's infoframe refactoring changes. Fixed non modeset
case for HDR metadata update. Dropped a redundant patch.

v6: Addressed Shashank's review comments and added RB's received.

v7: Squashed 2 patches, dropped 1 change and addressed Brian Starkey's and
Shashank's review comments.

v8: Addressed Jonas Karlman review comments. Added Shashank's RB to the series,
fixed a WARN_ON on BYT/CHT.

v9: Addressed Ville and Jonas Karlman's review comments. Added the infoframe
state readout and metadata reference count.

Note: This is already tested with Kodi and a confirmation from team kodi has been
received. Branch details for the same as below:
