From: Niklas Cassel <niklas.cas...@wdc.com>
Define the structures and constants required to implement
Namespace Types support.
Namespace Types introduce a new command set, "I/O Command Sets",
that allows the host to retrieve the command sets associated with
a namespace. Introduce support for the command set and enable
detection for the NVM Command Set.
The new workflows for identify commands rely heavily on zero-filled
identify structs. E.g., certain CNS commands are defined to return
a zero-filled identify struct when an inactive namespace NSID
is supplied.
Add a helper function in order to avoid code duplication when
reporting zero-filled identify structures.
