drm/amd/display: Propagate HDMI RGB quantization selectability
DC uses dc_edid_caps.qs_bit when constructing the HDMI AVI InfoFrame
quantization-range field. Although DRM parses the sink capability into
drm_display_info, DM never copies it into the DC EDID capabilities. The
field therefore remains zero and the AVI quantization range stays at its
default value.
Copy rgb_quant_range_selectable for HDMI sinks and extend the existing
EDID-capability KUnit test to cover it.
