This patch initializes the iommu memory regions so that
PCIe end point transactions get translated. The translation
function is not yet implemented though.

This patch introduce domain and endpoint internal
datatypes. Both are stored in RB trees. The domain
owns a list of endpoints attached to it.
Helpers to get/put end points and domains are introduced.
get() helpers will become static in subsequent patches.
