drm/xe: Use hmm_range_fault to populate user pages
This is an effort to unify hmmptr (aka system allocator)
and userptr code. hmm_range_fault is used to populate
a virtual address range for both hmmptr and userptr,
instead of hmmptr using hmm_range_fault and userptr
using get_user_pages_fast.
This also aligns with AMD gpu driver's behavior. In
long term, we plan to put some common helpers in this
area to drm layer so it can be re-used by different
vendors.
-v1
use the function with parameter to confirm whether lock is
acquired by the caller or needs to be acquired in hmm_range_fault.
