    drm/xe/uapi, drm/xe: Make the PT code handle placement per PTE rather than per vma / range
    
    With SVM, ranges forwarded to the PT code for binding can, mostly
    due to races when migrating, point to both VRAM and system / foreign
    device memory. Make the PT code able to handle that by checking,
    for each PTE set up, whether it points to local VRAM or to system
    memory.
    
    The UAPI is changed implicitly in that before this patch,
    global atomics required a bo with VRAM/System placements. With
    this patch that is changed to requiring LR mode, and
    if the required placement is not available upon GPU atomic access
    pagefault, an error will be generated and the VM banned.
    
    v2:
    - Fix system memory GPU atomic access.
