At the point smmu_find_add_as() gets called, the bus number might
not be computed. Let's change the name of IOMMU memory region and
just use the devfn and an incrementing index.
The name only is used for debug.

smmu_iommu_mr() aims at returning the IOMMUMemoryRegion corresponding
to a given sid. The function extracts both the PCIe bus number and
the devfn to return this data. Current computation of devfn is wrong
as it only returns the PCIe function instead of slot | function.

Let's cache config data to avoid fetching and parsing STE/CD
structures on each translation. We invalidate them on data structure
invalidation commands.
We put in place a per-smmu mutex to protect the config cache. This
will be useful too to protect the IOTLB cache. The caches can be
accessed without BQL, ie. in IO dataplane. The same kind of mutex was
put in place in the intel viommu.

We set up the infrastructure to enumerate all the PCI devices
attached to the SMMU and create an associated IOMMU memory
region and address space.
Those info are stored in SMMUDevice objects. The devices are
grouped according to the PCIBus they belong to. A hash table
indexed by the PCIBus pointer is used. Also an array indexed by
the bus number allows to find the list of SMMUDevices.
