    AHCI - Fix PM probing issues, wait 10 seconds on physical port insertion
    
    * The spec is not completely clear on the point but CCB[1] *MUST* be used
      as the second CCB in a softreset sequence.  If it isn't, the wrong
      signature may be loaded into the signature register.
    
    * Wait 10 seconds on insertion of a physical port (we already wait 10 seconds
      on the insertion of a target behind a PM).
    
    * Do not cycle the PHY when doing a hard reset, it seems to create
      detection problems.
