[POWERPC] Read back MSI message in rtas_setup_msi_irqs() so restore works
There are plans afoot to use pci_restore_msi_state() to restore MSI
state after a device reset. In order for this to work for the RTAS MSI
backend, we need to read back the MSI message from config space after
it has been setup by firmware.
This should be sufficient for restoring the MSI state after a device
reset, however we will need to revisit this for suspend to disk if that
is ever implemented on pseries.
