    drm/xe/dgfx: Release mmap mappings on rpm suspend
    
    Release all mmap mappings for all vram objects which are associated
    with userfault such that, while pcie function in D3hot, any access
    to memory mappings will raise a userfault.
    
    Upon userfault, in order to access memory mappings, if graphics
    function is in D3 then runtime resume of dgpu will be triggered to
    transition to D0.
    
    Previous commit has blocked the rpm but let's make sure that rpm
    does not get blocked for headed cards(client's parts).
    Above pagefault approach will be  useful for headed cards to save the
    power when display is off and there are active mmap mappings.
    
    v2:
      - Add lock dep assertion before updating vram_userfault_count (Rodrigo)
      - Avoid iomem check before bo migration check as bo can migrate
        to system memory (Matthew Auld)
    v3:
      - Apply pagefault approach for headed cards.
