    Revert "mac80211 adjust QCA9561 PA bias"
    
    This reverts commit f9ff282d17ec652d63fa2404e47bb0e15ed95b69 as during
    upstream patch review process nbd pointed out, that this patch needs
    more work:
    
     "The patch looks wrong to me. I'm pretty sure that AR_CH0_TOP2 is the
      correct register, the definition has an explicit check for 9561 as well.
      I believe this patch works by accident because it avoids writing a wrong
      value to that register."
