x86, msi: Introduce x86_msi.compose_msi_msg call-back
This call-back points to the right function for initializing the msi_msg structure. The old code for msi_msg generation was split up into the irq-remapped and the default case. The irq-remapped case just calls into the specific Intel or AMD implementation when the device is behind an IOMMU. Otherwise the default function is called.
