drm/rockchip: inno_hdmi: Correctly setup HDMI quantization range

The display controller will always give full range RGB regardless of the
mode set, but HDMI requires certain modes to be transmitted in limited
range RGB. This is especially required for HDMI sinks which do not support
non-standard quantization ranges.

This enables color space conversion for those modes and sets the
quantization range accordingly in the AVI infoframe.
