    ahci: Add some DevSleep defintions. Recognize DevSleep link state.
    
    * Add the AHCI_PREG_SSTS_IPM_DEVSLEEP definition, and recognize
      the DevSleep power-state via the dev.ahci.X.Y.link_pwr_state sysctl.
    
    * Use AHCI_PREG_SSTS_* definitions in ahci_port_link_pwr_state(), instead
      of SATA_PM_SSTS_* ones.
    
    * Add CAP2 bits for DevSleep.
    
    * Add DEVSLP register definitions.
