drm/amd/display: Refine condition of cursor visibility for pipe-split

Browse source

[Why]
In some scenarios like fullscreen game, major plane is scaled. Then
if a upper layer owns the cursor, cursor is invisiable in the
majority of the screen.

[How]
Instead assuming upper plane handles cursor, summing up upper
split planes on the same layer. If whole upper plane covers current
half/whole pipe plane, disable cursor.
