Mapping a non-contiguous VRAM BO doesn't work, start to fix this.
v2:
- Include missing local change
v3:
- Use GPU for non-visible access
- Take PM ref in xe_ttm_access_memory
- Disable VMAP for non-contiguous BOs
v4:
- Fix less than page sized non-visible access
- Add PM ref to xe_ttm_access_memory
- Add PM ref to delayed snapshot capture worker
- Fix a couple of warnings in xe_res_cursor
- Test all possible code paths
