    drm/xe/xe2: Enable Priority Mem Read
    
    Enable feature to allow memory reads to take a priority memory path.
    This will reduce latency on the read path, but may introduce read after
    write (RAW) hazards as read and writes will no longer be ordered.
    
    To avoid RAW hazards, SW can use the MI_MEM_FENCE command or any other
    MI command that generates non posted memory writes.  This will ensure
    data is coherent in memory prior to execution of commands which read
    data from memory.
    
    No pattern identified in KMD that could lead to a hazard.
    
    v2: Modify commit message, enable priority mem read feature for media,
    modify version range, modify bspec detail (Matt Roper)
    
    v3: Rebase, fix cramped line-wrapping (jcavitt)
    
    v4: Rebase
    
    Bspec: 60298, 60237, 60187, 60188
