Thomas Moestl e8e2c56650 Revamp the busdma implementation a bit:
- change the IOMMU support code so that it supports overcommittting the
  available DVMA memory, while still allocating as lazily as possible.
  This is achieved by limiting the preallocation, and deferring the
  allocation to map load time when it fails. In the latter case, the
  DVMA memory reserved for unloaded maps can be stolen to free up enough
  memory for loading a map.
- allow NULL settings in the method tables, and search the parent tags
  until an appropriate implementation is found. This allows to remove some
  kluges in the old implementation.
