Add two HMP commands for inspecting emulated NVMe controllers from
the QEMU monitor without attaching gdb to the QEMU process:
- 'info nvme' - per-controller summary (PCI, identify
fields, CC/CSTS/AQA, queue counts)
- 'info nvme-queues' - per-queue listing of admin and I/O SQ/CQ
(size, head/tail, PRP1, doorbell offset,
phase tag)
Useful for verifying queue setup, doorbell rings, AERs held in the
admin SQ and similar driver/controller interaction details from a
running QEMU monitor.
