This is an effort to modify userptr code so it can be unified with
hmmptr.

A helper xe_userptr_populate_range is created to populate a user
page using hmm_range_fault, instead of using get_user_pages_fast.
This helper is then used to replace some userptr codes.

The same help will be used later for hmmptr.

The userptr invalidation code is also changed to match the hmmptr
behavior. We now destroy vma when userptr is munmapped from CPU.

This is part of the hmmptr (system allocator) codes. Since this
part can be merged separately, send it out for CI and review first.
It will be followed by other hmmptr codes.

Oak Zeng (4):
  drm/xe: Introduce helper to populate userptr
  drm/xe: Introduce a helper to free sg table
  drm/xe: Use hmm_range_fault to populate user pages
  drm/xe: destroy userptr vma on UNMAP event
