Add Plane Degamma Lut as a blob property. User will calculate
the lut values, create the blob and send it to driver using
this property. Lut calculation will be based on the gamma mode
chosen out of the gamma mode exposed.

drm: RFC for Plane Color
This is a RFC proposal for plane color hardware blocks.
It exposes the property interface to userspace and calls
out the details or interfaces created and the intended
purpose.

Define the structure with XE_LPD gamma lut ranges. HDR and SDR planes
have different capabilities, implemented respective structure for
the HDR planes. Degamma and GAMMA has same Lut caps for SDR planes,
extended the same.
Initialize the mode range caps as well.
