This patch series adds properties for plane color features. It adds
properties for degamma used to linearize data and CSC used for gamut
conversion. It also includes Gamma support used to again non-linearize
data as per panel supported color space. These can be utilize by user
space to convert planes from one format to another, one color space to
another etc.

Userspace can take smart blending decisions and utilize these hardware
supported plane color features to get accurate color profile. The same
can help in consistent color quality from source to panel taking
advantage of advanced color features in hardware.

These patches add the property interfaces and enable helper functions.
This series adds Intel's XE_LPD hw specific plane gamma feature. We
can build up and add other platform/hardware specific implementation
on top of this series.

Credits: Special mention and credits to Ville Syrjala for coming up
with a design for this feature and inputs. This series is based on
his original design and idea.

Note: Userspace support for this new UAPI will be done on Chrome. We
will notify the list once we have that ready for review.

ToDo: State readout for this feature will be added next.
