    drm/xe: Fix potential deadlock handling page faults
    
    Within a class the GuC will hault scheduling if the head of the queue
    can't be scheduled the queue will block. This can lead to deadlock if
    BCS0-7 all have faults and another engine on BCS0-7 is at head of the
    GuC scheduling queue as the migration engine used to fix tthe fault will
    be blocked. To work around this set the migration engine to the highest
    priority when servicing page faults.
