Joerg Roedel 241000556f x86/amd-iommu: Add device bind reference counting
This patch adds a reference count to each device to count
how often the device was bound to that domain. This is
important for single devices that act as an alias for a
number of others. These devices must stay bound to their
domains until all devices that alias to it are unbound from
the same domain.
