    AHCI - Bug fixes - primary port probe and TFD flushing.
    
    * The primary port probe was skipping the software reset step.
    
    * ahci_flush_tfd() was looping on the SERR.DIAG.X bit with a 10ms delay,
      but on some parts this bit gets re-set very quickly if the port is
      in a COMRESET state.  Remove the loop, just use an if() instead.
