This series introduces support for performing iova-to-phys translations via
the ARM SMMU hardware on supported implementations. We also make use of
some new generic macros for polling hardware registers.

v1..v2:

- Renamed one of the iopoll macros to use the more standard `_atomic'
suffix
- Removed some convenience iopoll wrappers to encourage explicitness

v2..v3:

- Removed unnecessary `dev_name's

v3..v4:

- Updated the iopoll commit message to reflect the patch better
- Added locking around address translation op
- Return 0 on iova_to_phys failure
