iommu/amd: Detect and enable guest vAPIC support
This patch introduces a new IOMMU driver parameter, amd_iommu_guest_ir,
which can be used to specify different interrupt remapping mode for
passthrough devices to VM guest:
* legacy: Legacy interrupt remapping (w/ 32-bit IRTE)
* vapic : Guest vAPIC interrupt remapping (w/ GA mode 128-bit IRTE)
Note that in vapic mode, it can also supports legacy interrupt remapping
for non-passthrough devices with the 128-bit IRTE.
