drm/amd/display: use full update for clip size increase of large plane source

Browse source

[why]
Clip size increase will increase viewport, which could cause us to
switch  to MPC combine.
If we skip full update, we are not able to change to MPC combine in
fast update. This will cause corruption showing on the video plane.

[how]
treat clip size increase of a surface larger than 5k as a full update.
