[RFC 19/33] drm/i915/color: Add SDR plane LUT range data to color pipeline

[Uma Shankar]

From: Chaitanya Kumar Borah <chaitanya.kumar.borah at intel.com>

Add LUT ranges for color blocks in SDR planes. Userspace can
parse through this information to generate proper LUT data for
respective hardware blocks. It will be exposed to the user space
by the color pipeline.
