We need a way to ask interrupt controller driver its MSI address, so we can add it to IOMMU domain on iommu context creation. This will allow a device to send MSI interrupts. One of the idea is to reuse MAP_MSI method with no valid IRQ argument. Or should we do that differently? See usage at https://reviews.freebsd.org/D24618
