gen_pcie_root_port: Add ACS (Access Control Services) capability

Claim ACS support in the generic PCIe root port to allow
passthrough of individual functions of a device to different
guests (in a nested virt.setting) with VFIO.
Without this patch, all functions of a device, such as all VFs of
an SR/IOV device, will end up in the same IOMMU group.
A similar situation occurs on Windows with Hyper-V.

In the single function device case, it also has a small cosmetic
benefit in that the root port itself is not grouped with
the device. VFIO handles that situation in that binding rules
only apply to endpoints, so it does not limit passthrough in
those cases.

pcie: Allow generic PCIe root port to specify link speed and width

Allow users to experimentally specify speed and width values for the
generic PCIe root port. Defaults remain at 2.5GT/s & x1 for
compatiblity with the intent to only support changing defaults via
machine types for now.

Note for libvirt testing that pcie-root-port controllers are given
default names like "pci.7" which don't play well with using the
"-set device.$name.$prop=$value" options accessible to us via
<qemu:commandline> options. The solution is to add an <alias> to the
pcie-root-port <controller>, for example:

<controller type='pci' index='7' model='pcie-root-port'>
<model name='pcie-root-port'/>
<target chassis='7' port='0x15'/>
<alias name='ua-gfx0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x5'/>
</controller>

The "ua-" here is a mandatory prefix. We can then use:

<qemu:commandline>
<qemu:arg value='-set'/>
<qemu:arg value='device.ua-gfx0.x-speed=8'/>
<qemu:arg value='-set'/>
<qemu:arg value='device.ua-gfx0.x-width=16'/>
</qemu:commandline>

or, without an alias, set globals such as:

<qemu:commandline>
<qemu:arg value='-global'/>
<qemu:arg value='pcie-root-port.x-speed=8'/>
<qemu:arg value='-global'/>
<qemu:arg value='pcie-root-port.x-width=16'/>
</qemu:commandline>

pci/bus: let it has higher migration priority

In the past, we prioritized IOMMU migration so that we have such a
priority order:

IOMMU > PCI Devices

When migrating a guest with both vIOMMU and

pci/bus: let it has higher migration priority

In the past, we prioritized IOMMU migration so that we have such a
priority order:

IOMMU > PCI Devices

When migrating a guest with both vIOMMU and a pcie-root-port, we'll
always migrate vIOMMU first, since pci buses will be seen to have the
same priority of general PCI devices.

That's problematic.

The thing is that PCI bus number information is stored in the root port,
and that is needed by vIOMMU during post_load(), e.g., to figure out
context entry for a device. If we don't have correct bus numbers for
devices, we won't be able to recover device state of the DMAR memory
regions, and things will be messed up.

So let's boost the PCIe root ports to be even with higher priority:

PCIe Root Port > IOMMU > PCI Devices

A smoke test shows that this patch fixes bug 1538953.

Also, apply this rule to all the PCI bus/bridge devices: ioh3420,
xio3130_downstream, xio3130_upstream, pcie_pci_bridge, pci-pci bridge,
i82801b11.

I noted that we set pcie_pci_bridge_dev_vmstate twice. Clean that up
together.

hw/pci: add QEMU-specific PCI capability to the Generic PCI Express Root Port

To enable hotplugging of a newly created pcie-pci-bridge,
we need to tell firmware (e.g. SeaBIOS) to reserve
additional buses or IO/MEM/PREF space for pcie-root-port.
Additional bus reservation allows us to hotplug pcie-pci-bridge into this root port.
The number of buses and IO/MEM/PREF space to reserve are provided to the device via
a corresponding property, and to the firmware via new PCI capability.
The properties' default values are -1 to keep default behavior unchanged.

pci: Convert msix_init() to Error and fix callers

msix_init() reports errors with error_report(), which is wrong when
it's used in realize(). The same issue was fixed for msi_init() in
commit 1108b

pci: Convert msix_init() to Error and fix callers

msix_init() reports errors with error_report(), which is wrong when
it's used in realize(). The same issue was fixed for msi_init() in
commit 1108b2f. In order to make the API change as small as possible,
leave the return value check to later patch.

For some devices(like e1000e, vmxnet3, nvme) who won't fail because of
msix_init's failure, suppress the error report by passing NULL error
object.

Bonus: add comment for msix_init.

hw/pcie: Introduce Generic PCI Express Root Port

The Generic Root Port behaves almost the same as the
Intel's IOH device with id 3420, without having
Intel specific attributes.

The device has two purposes:
(1) Can be used on both X86 and ARM machines.
(2) It will allow us to tweak the behaviour
(e.g add vendor-specific PCI capabilities)
- something that obviously cannot be done
on a known device.
