Changes in v11:
Addressed Rob comment on DT binding patch to set min/maxItems of reg property in else part.
Rebased on top of https://git.kernel.org/pub/scm/linux/kernel/git/will/linux.git/log/?h=for-joerg/arm-smmu/updates.

Changes in v10:
Perform SMMU base ioremap before calling implementation init.
Check for Global faults across both ARM MMU-500s during global interrupt.
Check for context faults across all contexts of both ARM MMU-500s during context fault interrupt.
Add new DT binding nvidia,smmu-500 for NVIDIA implementation.
