drm/amd/display: Fallback to SW cursor if SubVP + cursor too big
[Description]
- For SubVP cursor cannot be cached in MALL, therefore
we will switch to SW cursor if the cursor size exceeds
what can fit in the local DCN buffers (64x64x4)
- Returning false / failure for set_cursor_attributes will
fallback to SW cursor
