x86: Use x86_platform for iommu_shutdown
This patch cleans up pci_iommu_shutdown() a bit to use x86_platform (similar to how IA64 initializes an IOMMU driver). This adds iommu_shutdown() to x86_platform to avoid calling every IOMMUs' shutdown functions in pci_iommu_shutdown() in order. The IOMMU shutdown functions are platform specific (we don't have multiple different IOMMU hardware) so the current way is pointless. An IOMMU driver sets x86_platform.iommu_shutdown to the shutdown function if necessary.
