    nvme: Add OAES bit-field definitions
    
    Create definitions for the Optional Asynchronous Events Supported (OAES)
    values. Also adds a helper macro for the common use case of "mask and
    shift". E.g.
        value = NVME_CTRLR_DATA_OAES_NS_ATTR_MASK << NVME_CTRLR_DATA_OAES_NS_ATTR_SHIFT;
    becomes
        value = NVMEB(NVME_CTRLR_DATA_OAES_NS_ATTR);
    
    (cherry picked from commit e71afa1202750b7cc8d49e77b7eed0114ece1657)
