Enable PCI on the ARM PVH machine. First we add a way to control the use
of buffered IOREQ's since those are not supported on Xen/ARM.
Finally we enable the PCI support.

I've published some instructions on how to try this including the work in
progress Xen side of the PVH PCI support:
https://github.com/edgarigl/docs/blob/master/xen/pvh/virtio-pci-dom0less.md

Cheers,
Edgar

ChangeLog:

v1 -> v2:
* Change handle_ioreq from int to uint8_t.
* Fallback to legacy API if buffered ioreqs are enabled and also if
  the new API is not supported. Clarify with comments.
