Nicola Corna 8fea4a102c x86/64: enable IOMMU support
Enable IOMMU support for Intel and AMD x86 platforms. With this, when the
vfio module is present, physical PCI devices can be passed to VMs, for
example with `qemu-system-x86_64 -device vfio-pci,host=05:00.0 ...`.

IOMMU support increases the kernel size by a small amount (~370KB, from
5239840 B to 5611200 B, a ~7% increase in size).

option. Move it to generic kernel configuration and also activate it for
malta.
