This ops is used to iterate over GPUVA's in the user-provided range

range lies within it. The operations can create up to 2 REMAPS and 2 MAPs.
The primary use case is for drivers to assign attributes to GPU VAs in
the specified range without performing unmaps or merging mappings,
supporting fine-grained control over sparse va's.
v2
- use drm_gpuvm_sm_map_ops_create with flags instead of defining new
ops_create (Danilo)
- Add doc (Danilo)
v3
- Fix doc
- Fix unmapping check
v4
- Fix mapping for non madvise ops
v5
- Fix mapping (Matthew Brost)
- Rebase on top of struct changes
v6
- flag moved to map_req
v7 (Danilo)
- Use different functions
- Add kernel-doc
- Modify op_unmap_cb and op_map_cb to handle madvise and NULL ptr
- use gem_obj check in single place

This looks pretty clean now, and thanks for adding the documentation.

Feel free to take this through the Xe tree if necessary.
Thanks
