commit af1be04901e27ce669b4ecde1c953d5c939498f5 upstream.
On some systems the IVRS table does not contain all PCI
devices present in the system. In case a device not present
in the IVRS table is translated by the IOMMU no DMA is
possible from that device by default.
This patch fixes this by removing the DTE entry for every
PCI device present in the system and not covered by IVRS.

Convert the AMD IOMMU driver to use the new interface for
publishing the iommu_ops.

The shift direction was wrong because the function takes a
page number and i is the address is the loop.

The domain_flush_devices() function takes the domain->lock.
But this function is only called from update_domain() which
itself is already called unter the domain->lock. This causes
a deadlock situation when the dma-address-space of a domain
grows larger than 1GB.

The value is only set to true but never set back to false,
which causes to many completion-wait commands to be sent to
hardware. Fix it with this patch.

Reserve the MSI address range in the address allocator so
that MSI addresses are not handed out as dma handles.

A few parts of the driver were missing in drivers/iommu.
Move them there to have the complete driver in that
directory.

This should ease finding similarities with different platforms,
with the intention of solving problems once in a generic framework
which everyone can use.
Compile-tested on x86_64.
