It seems it only gained its only user in b739f125e4eb ("i915: use
io_mapping_map_user") but reverted a month later by 0e4fe0c9f2f9 ("Revert
"i915: use io_mapping_map_user"") all that in 2021.

Ideally i915 would be converted again with the revert reasons investigated
properly this time. Otherwise we should remove the thing.
