mem: Add StreamID and SubstreamID
This patch adds StreamID and SubstreamID to Request. These fields can
be used by a SMMU/IOMMU model to pick up the correct translation
context for each request and they correspond to an ASID in a device.
For this reason they have been merged together with the request asid
in a union, so that a cpu will set the asid and a device will set
the Stream and Substream ID.
