nvme: Add OAES bit-field definitions

Browse Source 
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);
