[PATCH] NVMe: Update namespace and controller identity structures as per 1.1a spec

[Dimitri John Ledkov]

Controller: add CNTLID, AVSCC, APSTA, NVSCC, ACWU, SGLS fields.

Namespace: add NMIC, RESCAP, EUI64 fields. EUI64 is specifically
interesting, since it can be used to construct an UEFI NVMe device
path for a boot entry.

As per NVM Express 1.1a spec:
