This series adds the base support for MSI injection on Arm. This is
needed to streamline virtio-pci interrupt triggering.
With this patches, MSIs can be triggered in guests by issuing the new
DM op, inject_msi2. This op is similar to inject_msi, but it allows
to specify the source id of the MSI.
We chose the approach of adding a new DM op instead of using the pad
field of inject_msi because we have no clear way of distinguishing
between set and unset pad fields. New implementations also adds flags
field to clearly specify if the SBDF is set.
Patches were tested on QEMU with

patches for ITS support for DomUs applied.
This means this series is unusable without external patches. Given this
is adding a new DM operations, I think it would be more sensible to have
the vITS support merged first. Then we can look at merging this series.
