drm/nouveau: set RGB quantization range to FULL
The nouveau driver outputs full range RGB, but the AVI InfoFrame just says
'Default' instead of 'Full'.
Call drm_hdmi_avi_infoframe_quant_range to fill in the quantization field
of the AVI InfoFrame correctly. Now displays that advertise RGB Selectable
Quantization Range in their EDID will understand that full range is
transmitted by the HDMI output. This is consistent to how the Nvidia's
driver behaves.
