iommu/amd: Adding GALOG interrupt handler
This patch adds AMD IOMMU guest virtual APIC log (GALOG) handler.
When IOMMU hardware receives an interrupt targeting a blocking vcpu,
it creates an entry in the GALOG, and generates an interrupt to notify
the AMD IOMMU driver.
At this point, the driver processes the log entry, and notify the SVM
driver via the registered iommu_ga_log_notifier function.
