This patch set addresses the review comments from [1].

The SMMUv2 and other compatibility changes have been broken out of SMMUv3
patch.

Similar to the RFCv2 all the IORT realted changes have been dropped in this
version as these will be covered by [2]. The IORT implementation has to
provide a Linux like API to the SMMUv3 driver.

List of changes:
- Addition of a linux_compat header.
- Addition of a common header for arm smmu defines.
- Rebase of the SMMUv3 driver to the driver in linux kernel 4.14 rc7.
- New config defines for ARM SMMU drivers.
