kernel: powerpc/iommu: Fix notifiers being shared by PCI and VIO buses

A slab-out-of-bounds read vulnerability was found in the Linux kernel's PowerPC IOMMU code. The failiommusetup function registers the same notifierblock structure to both PCI and VIO buses. Since notifierblock is a linked list node, this causes notifiers registered to one bus type to also apply t...
