hw/block/nvme: support Identify NS Attached Controller List
Support Identify command for Namespace attached controller list. This command handler will traverse the controller instances in the given subsystem to figure out whether the specified nsid is attached to the controllers or not. The 4096bytes Identify data will return with the first entry (16bits) indicating the number of the controller id entries. So, the data can hold up to 2047 entries for the controller ids.
