The existing code puts all devices from a root PE to the same IOMMU group.
However it is a possible situation when subordinate buses belong to
separate PEs, in this case devices from these subordinate buses
should be added to lower level PE rather to the root PE.

fm_drvs is an external variable. It is guaranteed to be zero,
opal_init() is called via a machine_subsys_initcall(). Due to a hack
in the eeh code the eeh driver is initialised with at the same
initcall level. This means depending on link ordering the following
error can occur because the opal irchip has not been initialised:

You should note that I started with scanning this patch for basic, say,
build system issues. Which I did find. But then I kept spotting all kind
of oddities. After a while I stopped looking closely. So, to note
something, I haven't yet looked into the 24 symbols this series exports.
