drm/amd/display: Account for cursor prefetch BW in DML1 mode support
[ Upstream commit 074b3a886713f69d98d30bb348b1e4cb3ce52b22 ]
[Description]
We need to ensure to take into account cursor prefetch BW in
mode support or we may pass ModeQuery but fail an actual flip
which will cause a hang. Flip may fail because the cursor_pre_bw
is populated during mode programming (and mode programming is
never called prior to ModeQuery).
