    x86: Use x86_platform for iommu_shutdown · 338bac52
    FUJITA Tomonori authored
    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.
