It looks this was accidently lost in a follow up patch.
dc context is large and we don't need contiguous pages.
Fixes: e4863f118a7d ("drm/amd/display: Multi display cause system lag on mode change")

Did a quick test, it seems to resolve the issue for me. If you could
apply one or both of:
Reported-by: Alex Xu (Hello71) <alex_y_xu@yahoo.ca>
Tested-by: Alex Xu (Hello71) <alex_y_xu@yahoo.ca>
I'd appreciate it, but it's not a big deal. Thanks!
