Log Message:
add support for using MSI for XenPV Dom0
use PHYSDEVOP_map_pirq to get the pirq/gsi for MSI/MSI-X, switch also INTx
to use it instead of PHYSDEVOP_alloc_irq_vector
MSI confirmed working with single-vector MSI for wm(4), ahcisata(4), bge(4)
XXX added some provision for MSI-X, but it doesn't actually work (no interrupts
delivered), needs some further investigation; disable MSI-X for XENPV
via flag in x86/pci/pci_machdep.c
