Some code cleanup:

- Fix some comments; remove numerous superfluous or outdated ones.
- Correctly pass on the requesting device when handing requests up
  to the parent bus.
- Use the complete device name, including unit number, to build the
  IOMMU instance name.
- Inline a function that was only used once, and was trivial.
