drm/amd/display: Allow spatial dither to 10 bpc on all DCE
Spatial dithering to 10 bpc depth was disabled for all DCE's.
Testing on DCE-8.3 and DCE-11.2 did not show any obvious ill
effects, but a measureable precision improvement (via colorimeter)
when displaying a fp16 framebuffer to a 10 bpc DP or HDMI connected
HDR-10 monitor.
v2: enable it for all DCEs (Alex)
