The proposal about virtio-iommu support page tables is being discussed in
the virtio-comment mailing list[1]. This patch-set based on Jean's
virtio-iommu/pgtables branch[2] tries to follow the proposal and add the
basic VT-d IO page table support to virtio-iommu.
On Intel platform with VT-d nested
The value of granule is ilog2(pgsize). When the value of pgsize isn't
a power of two, granule would make pgsize less than the actual size of
pgsize. E.g., if pgsize = 0x6000 and granule = ilog2(gather->pgsize), then
granule = 0xe. 2^0xe = 0x4000 makes the pgsize (0x4000) smaller than the
actual pgs
VT-d hardware cap/ecap information is needed for driver to generate VT-d
format IO page table. Add struct vtd_cfg to keep the info.

The generic IO page table framework provides a set of interfaces for
invoking IO page table operations. Other entity (e.g., virtio-iommu
driver) can use the interface to ask VT-d driver to generate a VT-d
format IO page table. This patch adds the support.
