    AHCI - Chip reset, Inquiry alignment, ATAPI adjustments, Intel attach
    
    * When resetting the chip set AE before issuing HR and leave AE set
      when issuing HR.  After reset is complete, set AE again.
    
    * Do Intel hocus pocus at config register 0x92 for Intel chipsets.
    
    * The only PIO request is basically the initial INQUIRY during probe.
      Make sure the structure does not cross a page boundary so only one
      DRQ buffer is needed.  Very old AHCI chipsets may need this.
    
    * Make minor flags adjustments for PIO setup commands during the
      initial probe.
    
    * Reduce verbosity slightly.
