drm/i915: Provide the quantization range in the AVI infoframe
The AVI infoframe is able to inform the display whether the source is
sending full or limited range RGB data.
As per CEA-861 [1] we must first check whether the display reports the
quantization range as selectable, and if so we can set the approriate
bits in the AVI inforframe.
[1] CEA-861-E - 6.4 Format of Version 2 AVI InfoFrame
v2: Give the Q bits better names, add spec chapter information
