drm/amd/display: Request HW cursor on DCN3.2 with SubVP

Browse Source 
[ Upstream commit b74f46f3ce1e5f6336645f1e9ff47c56d5dfdef1 ]

[why]
When SubVP is active the HW cursor size is limited to 64x64, and
anything larger will force composition which is bad for gaming on
DCN3.2 if the game uses a larger cursor.

[how]
If HW cursor is requested, typically by a fullscreen game, do not
enable SubVP so that up to 256x256 cursor sizes are available for
DCN3.2.
