    drm/xe/xe2: Add Wa_15015404425
    
    Wa_15015404425 asks us to perform four "dummy" writes to a
    non-existent register offset before every real register read.
    Although the specific offset of the writes doesn't directly
    matter, the workaround suggests offset 0x130030 as a good target
    so that these writes will be easy to recognize and filter out in
    debugging traces.
    
    V4(MattR):
      - Use writel and remove xe_reg usage
    V3(MattR):
      - Define dummy reg local to function
      - Avoid tracing dummy writes
      - Update commit message
    V2:
      - Add WA to 8/16/32bit reads also - MattR
      - Corrected dummy reg address - MattR
      - Use for loop to avoid mental pause - JaniN
