iommu/amd: Implements irq_set_vcpu_affinity() hook to setup vapic mode for pass-through devices
This patch implements irq_set_vcpu_affinity() function to set up interrupt
remapping table entry with vapic mode for pass-through devices.
In case requirements for vapic mode are not met, it falls back to set up
the IRTE in legacy mode.
