scsi: qla2xxx: Dual FCP-NVMe target port support
Some storage arrays advertise FCP LUNs and NVMe namespaces behind the same
WWN. The driver now offers a user option by way of NVRAM parameter to
allow users to choose, on a per port basis, the kind of FC-4 type they
would like to prioritize for login.
