Subject: drm/radeon: fix HDMI quantization_range for pre-DCE5 asics

From: Alex Deucher <alexander.deucher@amd.com>

commit 86b7709d48f0df8796bddd7e1ce45c6fb7a7c6ec upstream.

Support for output_csc is only available on DCE5 and newer so
don't mess with the HDMI quantization_range on pre-DCE5 asics.
