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.

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.
