scsi: qla2xxx: Add FC-NVMe F/W initialization and transport registration
This code provides the interfaces to register remote and local ports of FC4 type 0x28 with the FC-NVMe transport and transports the requests (FC-NVMe FC link services and FC-NVMe commands IUs) to the fabric. It also provides the support for allocating h/w queues and aborting FC-NVMe FC requests.
