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



[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.
