drm/radeon: Use drm_hdmi_avi_infoframe_quant_range()
Fill out the AVI infoframe quantization range bits using drm_hdmi_avi_infoframe_quant_range() instead of hand rolling it. This changes the behaviour slightly as drm_hdmi_avi_infoframe_quant_range() will set a non-zero Q bit even when QS==0 iff the Q bit matched the default quantization range for the given mode. This matches the recommendation in HDMI 2.0 and is allowed even before that.
