Chaitanya Kumar Borah 1ae15b6c79 drm/i915/dp: Fix VSC dynamic range signaling for RGB formats 
For RGB, set dynamic_range to CTA or VESA based on
crtc_state->limited_color_range so sinks apply correct
quantization. YCbCr remains limited (CTA) range.
(DP v1.4, Table 5-1)

v2:
- Added Reported-by and Tested-by tags

v3:
- Add back YCbCr comment(Suraj)

Cc: stable@vger.kernel.org #v5.8+

Closes: https://gitlab.freedesktop.org/drm/i915/kernel/-/work_items/15874
Tested-by: DeepChirp <DeepChirp@outlook.com>
