pseries: Add PCI MSI/MSI-X support
This patch implements MSI and MSI-X support for the pseries PCI host
bridge. To do this it adds:
* A "config_space_address to msi_table" map, since the MSI RTAS calls
take a PCI config space address as an identifier.
* A MSIX memory region to catch msi_notify()/msix_notiry() from
virtio-pci and pass them to the guest via qemu_irq_pulse().
* RTAS call "ibm,change-msi" which sets up MSI vectors for a
device. Note that this call may configure and return lesser number of
vectors than requested.
* RTAS call "ibm,query-interrupt-source-number" which translates MSI
vector to interrupt controller (XICS) IRQ number.
