hw/nvme: fix compliance issue wrt. iosqes/iocqes

As of prior to this patch, the controller checks the value of CC.IOCQES
and CC.IOSQES prior to enabling the controller. As reported by Ben in
GitLab issue #1691, this is not spec compliant. The controller should
only check these values when queues are created.

This patch moves these checks to nvme_create_cq(). We do not need to
check it in nvme_create_sq() since that will error out if the completion
queue is not already created.

Also, since the controller exclusively supports SQEs of size 64 bytes
and CQEs of size 16 bytes, hard code that.

hw/nvme: Implement the Function Level Reset

This patch implements the Function Level Reset, a feature currently not
implemented for the Nvme device, while listed as a mandatory ("shall")
in the 1.4 spec.

The implementation reuses FLR-related building blocks defined for the
pci-bridge module, and follows the same logic:
- FLR capability is advertised in the PCIE config,
- custom pci_write_config callback detects a write to the trigger
register and performs the PCI reset,
- which, eventually, calls the custom dc->reset handler.

Depending on reset type, parts of the state should (or should not) be
cleared. To distinguish the type of reset, an additional parameter is
passed to the reset function.

This patch also enables advertisement of the Power Management PCI
capability. The main reason behind it is to announce the no_soft_reset=1
bit, to signal SR-IOV support where each VF can be reset individually.

The implementation purposedly ignores writes to the PMCS.PS register,
as even such naïve behavior is enough to correctly handle the D3->D0
transition.

It’s worth to note, that the power state transition back to to D3, with
all the corresponding side effects, wasn't and stil isn't handled
properly.

hw/nvme: Add support for Secondary Controller List

Introduce handling for Secondary Controller List (Identify command with
CNS value of 15h).

Secondary controller ids are unique in the subsystem, hence they are
reserved by it upon initialization of the primary controller to the
number of sriov_max_vfs.

ID reservation requires the addition of an intermediate controller slot
state, so the reserved controller has the address 0xFFFF.
A secondary controller is in the reserved state when it has no virtual
function assigned, but its primary controller is realized.
Secondary controller reservations are released to NULL when its primary
controller is unregistered.

hw/nvme: 64-bit pi support

This adds support for one possible new protection information format
introduced in TP4068 (and integrated in NVMe 2.0): the 64-bit CRC guard
and 48-bit reference tag. This version does not support storage tags.

Like the CRC16 support already present, this uses a software
implementation of CRC64 (so it is naturally pretty slow). But its good
enough for verification purposes.

This may go nicely hand-in-hand with the support that Keith submitted
for the Linux kernel[1].

it's a u8. After a vmstate transfer, the new value could be wrong.

hw/nvme: fix endianess conversion and add controller list

Add the controller identifiers list CNS 0x13, available list of ctrls
in NVM Subsystem that may or may not be attached to namespaces.

In Identify Ctrl List of the CNS 0x12 and 0x13 no endian conversion
for the nsid field.

These two CNS values shows affect when there exists a Subsystem.
Added condition if there is no Subsystem return invalid field in
command.

hw/nvme: reimplement format nvm to allow cancellation

Prior to this patch, the aios associated with broadcast format are
submitted anonymously (no aiocb reference saved from the blk_aio call).

Fix this by formatting the namespaces one after another, saving a
reference to the aiocb for each.
