This patchset exploits the VFIO ZPCI CLP region, which provides hardware
information about passed-through s390 PCI devices that can be shared with
the guest.

The retrieval of this information is done once per function (and for a
subset of data, once per function group) and is performed at time of device
plug.  Some elements provided in the CLP region must still be forced to
default values for now to reflect what QEMU actually provides support for.

The original work for this feature was done by Pierre Morel.

Changes from v1:
- Added 2 patches to the front of this set that move the s390-pci-bus.h and
  s390-pci-inst.h files to include + associated MAINTAINERS hit.  These
  can be applied separately, but are included here for the sake of
  simplicity.
- Patch 4: header update placeholder refreshed to rc7
- Patch 5: Move new s390-pci-clp.h to include folder
- Patch 6+: s/grp/group/ and fallout from this
- Patch 9: Move new s390-pci-vfio.h to include folder
