AMD/IOMMU: consider hidden devices when flushing device I/O TLBs

Hidden devices are associated with DomXEN but usable by the
hardware domain. Hence they need flushing as well when all devices are
to have flushes invoked.

While there drop a redundant ATS-enabled check and constify the first
parameter of the involved function.
