    The ODD can be enabled for ZPODD if the following three conditions are
    satisfied:
    1 The ODD supports device attention;
    2 The platform can runtime power off the ODD through ACPI;
    3 The ODD is either slot type or drawer type.
    For such ODDs, zpodd_init is called and a new structure is allocated for
    it to store ZPODD related stuffs.
    
    And the zpodd_dev_enabled function is used to test if ZPODD is currently
    enabled for this ODD.
    
    A new config CONFIG_SATA_ZPODD is added to selectively build ZPODD code.
