drm/amd/display: Add debug option for allocating extra way for cursor

Browse source

[Why and How]
- Add a debug option for allocating extra way for cursor
- Remove usage of cache_cursor_addr since it's not gaurenteed
  to be populated
- Include cursor size in MALL calculation if it exceeds the
  DCN cursor buffer size (and don't need extra way for cursor)
